Protein Name:
U2 small nuclear ribonucleoprotein auxiliary factor 35 kDa subunit-related protein 2
|
UniprotKB/SwissProt ID: Q62377 (Q62377)
Gene Name:
Zrsr2
Organism: Mus musculus (Mouse)
Function: Pre-mRNA-binding protein required for splicing of both U2- and U12-type introns. Selectively interacts with the 3'-splice site of U2- and U12-type pre-mRNAs and promotes different steps in U2 and U12 intron splicing. Recruited to U12 pre-mRNAs in an ATP-dependent manner and is required for assembly of the prespliceosome, a precursor to other spliceosomal complexes. For U2-type introns, it is selectively and specifically required for the second step of splicing (By similarity)
