Protein: U2 small nuclear ribonucleoprotein A' (U2 snRNP A') (Looks exceptionally like U2A protein 1) (Q08963)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Involved in pre-mRNA splicing. Associates to U2 snRNA in a MSL1 dependent manner and is required for normal accumulation of U2 snRNA. Required for the spliceosome assembly and the efficient addition of U2 snRNP onto the pre-mRNA.
Subcellular location: Nucleus {ECO:0000269|PubMed:14562095}.
