molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0017070 | | U6 snRNA binding | | Interacting selectively and non-covalently with the U6 small nuclear RNA (U6 snRNA). |
| GO:0003676 | | nucleic acid binding | | Interacting selectively and non-covalently with any nucleic acid. |
| GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| 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). |
| GO:0017069 | | snRNA binding | | Interacting selectively and non-covalently with a small nuclear RNA (snRNA). |
biological process |
| 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: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:0000245 | | spliceosomal complex assembly | | The aggregation, arrangement and bonding together of a spliceosomal complex, a ribonucleoprotein apparatus that catalyzes nuclear mRNA splicing via transesterification reactions. |
| GO:0000244 | | spliceosomal tri-snRNP complex assembly | | The formation of a tri-snRNP complex containing U4 and U6 (or U4atac and U6atac) snRNAs and U5 snRNAs and associated proteins. This includes reannealing of U4 and U6 (or U4atac and U6atac) snRNAs released from previous rounds of splicing to reform the U4/U6 snRNP (or U4atac/U6atac snRNP) as well as the subsequent association of the U5 snRNP with the U4/U6 snRNP (or U4atac/U6atac snRNP) to form a tri-snRNP that is ready to reassemble into another spliceosome complex. |
cellular component |
| GO:0005688 | | U6 snRNP | | A ribonucleoprotein complex that contains small nuclear RNA U6. |
| 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. |
