Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Plays a role in pre-mRNA splicing and 3'-end processing (PubMed:17024186). By recruiting PRPF19 and the PRP19C/Prp19 complex/NTC/Nineteen complex to the RNA polymerase II C-terminal domain (CTD), and thereby pre-mRNA, may couple transcription to splicing (PubMed:21536736). Induces cardiac troponin-T (TNNT2) pre-mRNA exon inclusion in muscle. Regulates the TNNT2 exon 5 inclusion through competition with MBNL1. Binds preferentially to a single-stranded structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Required for the export of mRNA out of the nucleus, even if the mRNA is encoded by an intron-less gene. Represses the splicing of MAPT/Tau exon 10. Positively regulates pre-mRNA 3'-end processing by recruiting the CFIm complex to cleavage and polyadenylation signals (PubMed:17024186).SUBUNIT Interacts with U2AF1L4 (By similarity). Heterodimer with U2AF1 (PubMed:11551507). Binds unphosphorylated SF1 (PubMed:10449420, PubMed:12718882). Interacts with SCAF11 and SNW1 (PubMed:21460037, PubMed:9447963). Interacts with ZRSR2/U2AF1-RS2. Interacts with RBM17 (PubMed:17589525). Interacts with PRPF19; the interaction is direct. Interacts with POLR2A (via the C-terminal domain); recruits PRPF19 and the Prp19 complex to the pre-mRNA (PubMed:21536736). Interacts with KHDC4 (Isoform 2) (PubMed:19641227). Interacts with ZRSR2 (PubMed:9237760). Interacts with the SF3B complex composed of SF3B1, SF3B2, SF3B3, SF3B4, SF3B5, SF3B6 and PHF5A (PubMed:27720643). Interacts (via N-terminus) with CPSF7 (via C-terminus); this interaction stimulates pre-mRNA 3'-end processing by promoting the recruitment of the CFIm complex to cleavage and polyadenylation signals (PubMed:17024186). Interacts with ARGLU1; interaction may be involved in ARGLU1-mediated modulation of alternative splicing (PubMed:30698747).INTERACTION Lysyl-hydroxylation at Lys-15 and Lys-276 affects the mRNA splicing activity of the protein, leading to regulate some, but not all, alternative splicing events.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the splicing factor SR family.
