molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0000339 | | RNA cap binding | | Interacting selectively and non-covalently with a 7-methylguanosine (m7G) group or derivative located at the 5' end of an RNA molecule. |
| GO:0003729 | | mRNA binding | | Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
biological process |
| GO:0006370 | | 7-methylguanosine mRNA capping | | Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript. |
| GO:0016070 | | RNA metabolic process | | The cellular chemical reactions and pathways involving RNA, ribonucleic acid, one of the two main type of nucleic acid, consisting of a long, unbranched macromolecule formed from ribonucleotides joined in 3',5'-phosphodiester linkage. |
| GO:0008380 | | RNA splicing | | The process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA. |
| GO:0045292 | | mRNA cis splicing, via spliceosome | | The joining together, after removal of an intervening sequence composed of one or more introns, of two segments of the same RNA molecule via spliceosomal catalysis to produce an mRNA composed only of exon sequences that all came from the same primary transcript. |
| GO:0006397 | | mRNA processing | | Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. |
| GO:0000398 | | mRNA splicing, via spliceosome | | The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced. |
| GO:0051028 | | mRNA transport | | The directed movement of mRNA, messenger ribonucleic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| GO:0000184 | | nuclear-transcribed mRNA catabolic process, nonsense-mediated decay | | The nonsense-mediated decay pathway for nuclear-transcribed mRNAs degrades mRNAs in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins. |
| GO:0006970 | | response to osmotic stress | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of solutes outside the organism or cell. |
| GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
cellular component |
| GO:0000243 | | commitment complex | | A spliceosomal complex that is formed by association of the U1 snRNP with the 5' splice site of an unspliced intron in an RNA transcript. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005846 | | nuclear cap binding complex | | A conserved heterodimeric protein complex that binds to the 5' terminal cap structure m7G(5')ppp(5')N of nascent eukaryotic RNA polymerase II transcripts such as pre-mRNA and U snRNA. The consists of proteins known as CBP20 and CBP80, binds to cap structures in the nucleus, and is involved in pre-mRNA splicing, 3'-end formation, and RNA nuclear export. |
| 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:0048471 | | perinuclear region of cytoplasm | | Cytoplasm situated near, or occurring around, the nucleus. |
| GO:0005844 | | polysome | | A multiribosomal structure representing a linear array of ribosomes held together by messenger RNA. They represent the active complexes in cellular protein synthesis and are able to incorporate amino acids into polypeptides both in vivo and in vitro. |
