靶點詳情

  • 功能:
    Plays a role in pre-mRNA splicing and 3'-end processing. 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. 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.

    2. Data suggest that one way heterogeneous nuclear ribonucleoprotein A1 (HNRNPA1) regulates exon definition is to modulate the interaction of U2 small nuclear RNA auxiliary factor 2 (U2AF2) with decoy or bona fide 3' splice site (3'ss). PMID: 29650551

PMID: 27927715
