Enables U2 snRNA binding activity. Involved in mRNA splicing, via spliceosome. Part of U2-type prespliceosome. Human ortholog(s) of this gene implicated in connective tissue disease. Orthologous to human SNRPA (small nuclear ribonucleoprotein polypeptide A) and SNRPB2 (small nuclear ribonucleoprotein polypeptide B2).
SGD Description
U2B component of U2 snRNP; involved in splicing, binds the U2 snRNA stem-loop IV in vitro but requires association of Lea1p for in vivo binding; does not contain the conserved C-terminal RNA binding domain found in other family members
