RNA-binding protein that regulates alternative splicing events by binding to 5′-UGCAUGU-3′ elements. Prevents binding of U2AF2 to the 3′-splice site. Regulates alternative splicing of tissue-specific exons and of differentially spliced exons during erythropoiesis (By similarity). RNA-binding protein that seems to act as a coregulatory factor of ER-alpha. Together with RNA binding proteins RBPMS and MBNL1/2, activates vascular smooth muscle cells alternative splicing events (PubMed:37548402).
