CC -!- FUNCTION: Plays a role in pre-mRNA splicing and 3'-end processing CC (PubMed:17024186). By recruiting PRPF19 and the PRP19C/Prp19 CC complex/NTC/Nineteen complex to the RNA polymerase II C-terminal domain CC (CTD), and thereby pre-mRNA, may couple transcription to splicing CC (PubMed:21536736). Induces cardiac troponin-T (TNNT2) pre-mRNA exon CC inclusion in muscle. Regulates the TNNT2 exon 5 inclusion through CC competition with MBNL1. Binds preferentially to a single-stranded CC structure within the polypyrimidine tract of TNNT2 intron 4 during CC spliceosome assembly. Required for the export of mRNA out of the CC nucleus, even if the mRNA is encoded by an intron-less gene. Represses CC the splicing of MAPT/Tau exon 10. Positively regulates pre-mRNA 3'-end CC processing by recruiting the CFIm complex to cleavage and CC polyadenylation signals (PubMed:17024186). CC {ECO:0000269|PubMed:15009664, ECO:0000269|PubMed:17024186, CC ECO:0000269|PubMed:19470458, ECO:0000269|PubMed:19574390, CC ECO:0000269|PubMed:21536736}. CC -!- SUBUNIT: Interacts with U2AF1L4 (By similarity). Heterodimer with U2AF1 CC (PubMed:11551507). Binds unphosphorylated SF1 (PubMed:10449420, CC PubMed:12718882). Interacts with SCAF11 and SNW1 (PubMed:9447963, CC PubMed:21460037). Interacts with ZRSR2/U2AF1-RS2. Interacts with RBM17 CC (PubMed:17589525). Interacts with PRPF19; the interaction is direct. CC Interacts with POLR2A (via the C-terminal domain); recruits PRPF19 and CC the Prp19 complex to the pre-mRNA (PubMed:21536736). Interacts with CC KHDC4 (Isoform 2) (PubMed:19641227). Interacts with ZRSR2 CC (PubMed:9237760). Interacts with the SF3B complex composed of SF3B1, CC SF3B2, SF3B3, SF3B4, SF3B5, SF3B6 and PHF5A (PubMed:27720643). CC Interacts (via N-terminus) with CPSF7 (via C-terminus); this CC interaction stimulates pre-mRNA 3'-end processing by promoting the CC recruitment of the CFIm complex to cleavage and polyadenylation signals CC (PubMed:17024186). {ECO:0000250|UniProtKB:P26369, CC ECO:0000269|PubMed:10449420, ECO:0000269|PubMed:11551507, CC ECO:0000269|PubMed:12176931, ECO:0000269|PubMed:12718882, CC ECO:0000269|PubMed:17024186, ECO:0000269|PubMed:17589525, CC ECO:0000269|PubMed:19641227, ECO:0000269|PubMed:21460037, CC ECO:0000269|PubMed:21536736, ECO:0000269|PubMed:27720643, CC ECO:0000269|PubMed:9237760, ECO:0000269|PubMed:9447963}.
