PTBP2

Entrez Summary: N/A
UniProt Summary: RNA-binding protein which binds to intronic polypyrimidine tracts and mediates negative regulation of exons splicing. May antagonize in a tissue-specific manner the ability of NOVA1 to activate exon selection. In addition to its function in pre-mRNA splicing, plays also a role in the regulation of translation. Isoform 5 has a reduced affinity for RNA. {ECO:0000269|PubMed:11003644, ECO:0000269|PubMed:12667457}.
