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. Binds to polypyrimidine-rich controlling element (PCE) of CFTR and promotes exon skipping of CFTR exon 9, thereby antagonizing TIA1 and its role in exon inclusion of CFTR exon 9. Plays a role in the splicing of pyruvate kinase PKM by binding repressively to a polypyrimidine tract flanking PKM exon 9, inhibiting exon 9 inclusion and resulting in exon 10 inclusion and production of the PKM M2 isoform"],"length":531,"sequence":"MDGIVPDIAVGTKRGSDELFSACVTNGPFIMSSNSASTANGNDSKKFKGDSRSAGVPSRVIHVRKLPSDVTEGEVISLGLPFGKVTNLLMLKGKNQAFIEMNTEEAANTMVNYYTSVTPVLRGQPIYIQFSNHKELKTDSSPNQARAQAALQAVNSVQSGNLALAASAAAVDAGMAMAGQSPVLRIIVENLFYPVTLDVLHQIFSKFGTVLKIITFTKNNQFQALLQYADPMSAQHAKLSLDGQNIYNACCTLRIDFSKLTSLNVKYNNDKSRDYTRPDLPSGDSQPALDQTVAAAFGLSVPNVHGALAPLAIPSAAAAAAAAGRIAIPGLAGAGNSVLLVSNLNPERVTPQSLFILFGVYGDVQRVKILFNKKENALVQMADGSQAQLALSHLNGHKLHGKPVRITLSKHQNVQLPREGQEDQGLTKDYGNSPLHRFKKPGSKNFQNIFPPSATLHLSNIPPSVSEDDLKMLFSSNGGVVKGFKFFQKDRKMALIQMGSVEEAIQALIDLHNHDLGENHHLRVSFSKSTI","proteome":"UP000694856","gene":"PTBP1","go_terms":[{"identifier":"GO:0003676","name":"nucleic acid binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0003723","name":"RNA binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0006397","name":"mRNA processing","category":{"code":"P","name":"biological_process"}},{"identifier":"GO:0005634","name":"nucleus","category":{"code":"C","name":"cellular_component"}}],"protein_evidence":4,"source_database":"unreviewed","is_fragment":false,"in_alphafold":true,"in_bfvd":false,"ida_accession":"f27554d3635eebc058e54b0d262d221e47f541b9","counters":{"domain_architectures":1054,"entries":20,"isoforms":0,"proteomes":1,"sets":2,"structures":0,"taxa":1,"dbEntries":{"cathgene3d":1,"ssf":1,"pfam":3,"cdd":3,"profile":1,"smart":1,"panther":1,"ncbifam":1,"interpro":8},"proteome":1,"taxonomy":1,"similar_proteins":1054}}}
