| biological process |
|---|
| | GO:0006396 | | RNA processing | | Any process involved in the conversion of one or more primary RNA transcripts into one or more mature RNA molecules. |
| | GO:0000494 | | box C/D snoRNA 3'-end processing | | Any process involved in forming the mature 3' end of a box C/D snoRNA molecule. |
| | GO:1990258 | | histone glutamine methylation | | The modification of a histone by addition of a methyl group to an glutamine residue. |
| | GO:0032259 | | methylation | | The process in which a methyl group is covalently attached to a molecule. |
| | GO:0001649 | | osteoblast differentiation | | The process whereby a relatively unspecialized cell acquires the specialized features of an osteoblast, a mesodermal or neural crest cell that gives rise to bone. |
| | GO:0031167 | | rRNA methylation | | The posttranscriptional addition of methyl groups to specific residues in an rRNA molecule. |
| | GO:0006364 | | rRNA processing | | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. |
| | GO:0048254 | | snoRNA localization | | Any process in which small nucleolar RNA is transported to, or maintained in, a specific location. |
| | GO:0016074 | | snoRNA metabolic process | | The chemical reactions and pathways involving snoRNA, small nucleolar RNA, any of a class of small RNAs that are associated with the eukaryotic nucleus as components of small nucleolar ribonucleoproteins. They participate in the processing or modifications of many RNAs, mostly ribosomal RNAs (rRNAs) though snoRNAs are also known to target other classes of RNA, including spliceosomal RNAs, tRNAs, and mRNAs via a stretch of sequence that is complementary to a sequence in the targeted RNA. |
| | GO:0008033 | | tRNA processing | | The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group. |
| cellular component |
|---|
| | GO:0015030 | | Cajal body | | A class of nuclear body, first seen after silver staining by Ramon y Cajal in 1903, enriched in small nuclear ribonucleoproteins, and certain general RNA polymerase II transcription factors; ultrastructurally, they appear as a tangle of coiled, electron-dense threads roughly 0.5 micrometers in diameter; involved in aspects of snRNP biogenesis; the protein coilin serves as a marker for Cajal bodies. Some argue that Cajal bodies are the sites for preassembly of transcriptosomes, unitary particles involved in transcription and processing of RNA. |
| | GO:0031428 | | box C/D snoRNP complex | | A ribonucleoprotein complex containing small nucleolar RNA of the box C/D type that can carry out ribose-2'-O-methylation of target RNAs. |
| | GO:0001651 | | dense fibrillar component | | A structure found in the nucleolus, which contains newly synthesized preribosomal RNA (pre-rRNA) and a collection of proteins. |
| | GO:0070062 | | extracellular exosome | | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. |
| | GO:0001652 | | granular component | | A structure found in the nucleolus, which contains nearly completed preribosomal particles destined for the cytoplasm. |
| | GO:0030529 | | intracellular ribonucleoprotein complex | | An intracellular macromolecular complex containing both protein and RNA molecules. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0005730 | | nucleolus | | A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome. |
| | GO:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
| | 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. |
| | GO:0032040 | | small-subunit processome | | A large ribonucleoprotein complex that is an early preribosomal complex. In S. cerevisiae, it has a size of 80S and consists of the 35S pre-rRNA, early-associating ribosomal proteins most of which are part of the small ribosomal subunit, the U3 snoRNA and associated proteins. |
