  • Western blot analysis of extracts from Jurkat(lane 2(20ug) and Jurkat(lane 3(40ug) using U2AF2 Antibody (HY-P82476) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P83730, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

  • Immunohistochemical analysis of paraffin-embedded mouse liver tissue using U2AF2 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/100 dilution in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background
Function：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)
Subcellular Localization：Nucleus
Isoforms & Post-Translational Modification：P26368 has 2 isomers: P26368-1: 53501 Da (predicted); P26368-2: 53121 Da (predicted).
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
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)

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
