[[https://www.uniprot.org/uniprot/PTBP1_HUMAN PTBP1_HUMAN]] Plays a role in pre-mRNA splicing and in the regulation of alternative splicing events. Activates exon skipping of its own pre-mRNA during muscle cell differentiation. Binds to the polypyrimidine tract of introns. May promote RNA looping when bound to two separate polypyrimidine tracts in the same pre-mRNA. May promote the binding of U2 snRNP to pre-mRNA. Cooperates with RAVER1 to modulate switching between mutually exclusive exons during maturation of the TPM1 pre-mRNA. Represses the splicing of MAPT/Tau exon 10.<ref>PMID:11003644</ref> <ref>PMID:15009664</ref> <ref>PMID:16260624</ref> <ref>PMID:21518792</ref> <ref>PMID:16179478</ref>
