| molecular function |
|---|
| | GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| | GO:0000980 | | RNA polymerase II distal enhancer sequence-specific DNA binding | | Interacting selectively and non-covalently with a RNA polymerase II (Pol II) distal enhancer. In mammalian cells, enhancers are distal sequences that increase the utilization of some promoters, and can function in either orientation and in any location (upstream or downstream) relative to the core promoter. |
| | GO:0001158 | | enhancer sequence-specific DNA binding | | Interacting selectively and non-covalently with a specific sequence of DNA that is part of an enhancer, a transcription regulatory region that is somewhat distal from the core promoter and which enhances transcription from that promoter. |
| | GO:0001078 | | proximal promoter DNA-binding transcription repressor activity, RNA polymerase II-specific | | A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within a proximal promoter regulatory region of a RNA polymerase II-transcribed gene to repress or decrease transcription. |
| | GO:0043565 | | sequence-specific DNA binding | | Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding. |
| biological process |
|---|
| | GO:0007487 | | analia development | | The process whose specific outcome is the progression of the analia over time, from its formation to the mature structure. The analia is the posterior-most vertral appendage that develops from the genital disc. An example of this process is analia development in Drosophila melanogaster. |
| | GO:0021960 | | anterior commissure morphogenesis | | Generation of a long process of a CNS neuron, that carries efferent (outgoing) action potentials from the cell body in one half of the cerebral cortex towards target cells in the contralateral half. This axonal process is a member of those that make up the anterior commissure, a small midline fiber tract that lies at the anterior end of the corpus callosum. |
| | GO:0035288 | | anterior head segmentation | | Partitioning the insect head anlage into procephalic (labral, (ocular), antennal and intercalary) segments. The procephalic segments lie anterior to the gnathal (posterior head) segments, and are pattered by different segmentation gene cascades to the abdominal, thoracic and posterior head (gnathal) segments. |
| | GO:0048099 | | anterior/posterior lineage restriction, imaginal disc | | Formation and/or maintenance of a lineage boundary between anterior and posterior compartments that cells cannot cross, thus separating the populations of cells in each compartment. |
| | GO:0007448 | | anterior/posterior pattern specification, imaginal disc | | The establishment, maintenance and elaboration of the anterior/posterior axis of the imaginal disc. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that rapidly develop into adult appendages during metamorphosis from larval to adult form. |
| | GO:0007411 | | axon guidance | | The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues. |
| | GO:0007417 | | central nervous system development | | The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord. |
| | GO:0007386 | | compartment pattern specification | | The regionalization process in which embryonic segments are divided into compartments that will result in differences in cell differentiation. |
| | GO:0035224 | | genital disc anterior/posterior pattern formation | | The establishment, maintenance and elaboration of the anterior/posterior axis of the genital disc. An anterior and posterior compartment form in each of the three genital disc primoridia (the female genital disc primordium, the male genital disc primordium and the anal primordium). |
| | GO:0035215 | | genital disc development | | Progression of the genital imaginal disc over time, from its initial formation through to its metamorphosis to form the adult terminalia, comprising the entire set of internal and external genitalia and analia. Both sexes of Drosophila have a single genital disc formed from the female and male genital primordia, and the anal primordium. The anal primordium develops in both sexes, forming either male or female analia. However, only one of the genital primordia develops in each sex, forming either the male or the female genitalia. |
| | GO:0008406 | | gonad development | | The process whose specific outcome is the progression of the gonad over time, from its formation to the mature structure. The gonad is an animal organ that produces gametes; in some species it also produces hormones. |
| | GO:0007447 | | imaginal disc pattern formation | | The regionalization process that results in defined areas of the imaginal disc that will undergo specific cell differentaiton. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult appendages (legs, antennae, wings, etc.) during metamorphosis from larval to adult form. |
| | GO:0007486 | | imaginal disc-derived female genitalia development | | The process whose specific outcome is the progression of the female genitalia over time, from formation as part of the genital disc to the mature structure. An example of this is found in Drosophila melanogaster. |
| | GO:0007485 | | imaginal disc-derived male genitalia development | | The process whose specific outcome is the progression of the male genitalia over time, from formation as part of the genital disc to the mature structure. An example of this is found in Drosophila melanogaster. |
| | GO:0007474 | | imaginal disc-derived wing vein specification | | The regionalization process in which the area of a imaginal disc-derived wing that will form a wing vein is specified. |
| | GO:0007275 | | multicellular organism development | | The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult). |
| | GO:0010629 | | negative regulation of gene expression | | Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form. |
| | GO:0000122 | | negative regulation of transcription by RNA polymerase II | | Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II. |
| | GO:0045892 | | negative regulation of transcription, DNA-templated | | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
| | GO:0007400 | | neuroblast fate determination | | The cell fate determination process in which a cell becomes capable of differentiating autonomously into a neuroblast cell regardless of its environment; upon determination, the cell fate cannot be reversed. An example of this process is found in Mus musculus. |
| | GO:0045944 | | positive regulation of transcription by RNA polymerase II | | Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| | GO:0007388 | | posterior compartment specification | | The process involved in the specification of cell identity in the posterior compartments of the segmented embryo. |
| | GO:0035289 | | posterior head segmentation | | Partitioning the posterior region of the insect head anlage into gnathal (mandibular, maxillary and labial) segments. Unlike the anterior head (procephalic) segments, formation of the posterior head (gnathal) segments occurs by a similar mechanism to trunk segmentation, where a cascade of gap genes, pair-rule genes and segment-polarity genes subdivide the embryo into progressively smaller domains. |
| | GO:0010468 | | regulation of gene expression | | Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form. |
| | GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| | GO:0007367 | | segment polarity determination | | Division of the 14 parasegments of the embryo into anterior and posterior compartments; exemplified by the actions of the segment polarity gene products. |
| | GO:0035277 | | spiracle morphogenesis, open tracheal system | | The process in which the anatomical structures of a spiracle are generated and organized. Spiracles are the openings in the insect open tracheal system; externally they connect to the epidermis and internally they connect to the tracheal trunk. |
| | GO:0006351 | | transcription, DNA-templated | | The cellular synthesis of RNA on a template of DNA. |
| | GO:0035290 | | trunk segmentation | | Partitioning of the blastoderm embryo into trunk segmental units. In Drosophila, the trunk segments include thoracic segments and abdominal segments A1 to A8. |
| | GO:0007418 | | ventral midline development | | The process whose specific outcome is the progression of the ventral midline over time, from its formation to the mature structure. In protostomes (such as insects, snails and worms) as well as deuterostomes (vertebrates), the midline is an embryonic region that functions in patterning of the adjacent nervous tissue. The ventral midline in insects is a cell population extending along the ventral surface of the embryo and is the region from which cells detach to form the ventrally located nerve cords. In vertebrates, the midline is originally located dorsally. During development, it folds inwards and becomes the ventral part of the dorsally located neural tube and is then called the ventral midline, or floor plate. |
| | GO:0048100 | | wing disc anterior/posterior pattern formation | | The establishment, maintenance and elaboration of the anterior/posterior axis of the wing disc, a precursor to the wing. |
| cellular component |
|---|
| | GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
