| molecular function |
|---|
| | GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| | GO:0030621 | | U4 snRNA binding | | Interacting selectively and non-covalently with the U4 small nuclear RNA (U4 snRNA). |

They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity. |

| | 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:1990381 | | ubiquitin-specific protease binding | | Interacting selectively and non-covalently with a ubiquitin-specific protease. |
| 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: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:0000902 | | cell morphogenesis | | The developmental process in which the size or shape of a cell is generated and organized. |
| | GO:0071425 | | hematopoietic stem cell proliferation | | The expansion of a hematopoietic stem cell population by cell division. A hematopoietic stem cell is a stem cell from which all cells of the lymphoid and myeloid lineages develop. |
| | GO:0048872 | | homeostasis of number of cells | | Any biological process involved in the maintenance of the steady-state number of cells within a population of cells. |
| | 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:0006334 | | nucleosome assembly | | The aggregation, arrangement and bonding together of a nucleosome, the beadlike structural units of eukaryotic chromatin composed of histones and DNA. |
| | GO:1903586 | | positive regulation of histone deubiquitination | | Any process that activates or increases the frequency, rate or extent of histone deubiquitination. |
| | 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: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:0000387 | | spliceosomal snRNP assembly | | The aggregation, arrangement and bonding together of one or more snRNA and multiple protein components to form a ribonucleoprotein complex that is involved in formation of the spliceosome. |
| | 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: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:0071001 | | U4/U6 snRNP | | A ribonucleoprotein complex that contains base-paired U4 and U6 small nuclear RNAs. |
| | GO:0046540 | | U4/U6 x U5 tri-snRNP complex | | A ribonucleoprotein complex formed by the association of the U4/U6 and U5 small nuclear ribonucleoproteins. |
| | GO:0071002 | | U4atac/U6atac snRNP | | A ribonucleoprotein complex that contains base-paired U4atac and U6atac small nuclear RNAs. |
| | GO:0005691 | | U6atac snRNP | | A ribonucleoprotein complex that contains small nuclear RNA U6atac. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0016607 | | nuclear speck | | A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy. |
| | 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. |
