Protein Structure
UniProt Annotation
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. {ECO:0000269PubMed:21041408, ECO:0000269PubMed:9237760}.
Subcellular Localization Nucleus {ECO:0000269PubMed:15146077}.
