Protein Name:
Splicing factor U2AF 26 kDa subunit
|
UniprotKB/SwissProt ID: Q7TP17 (Q7TP17)
Gene Name:
U2af1l4
Organism: Rattus norvegicus (Rat)
Function: RNA-binding protein that function as a pre-mRNA splicing factor. Plays a critical role in both constitutive and enhancer-dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3'-splice site selection. Acts by enhancing the binding of U2AF2 to weak pyrimidine tracts. Also participates in the regulation of alternative pre-mRNA splicing. Activates exon 5 skipping of PTPRC during T-cell activation; an event reversed by GFI1. Binds to RNA at the AG dinucleotide at the 3'-splice site. Shows a preference for AGC or AGA
