Predicted to enable U1 snRNA binding activity; mRNA binding activity; and zinc ion binding activity. Predicted to act upstream of or within mRNA 5'-splice site recognition and spliceosomal snRNP assembly. Predicted to be located in nucleus. Predicted to be part of U1 snRNP. Human ortholog(s) of this gene implicated in connective tissue disease; mixed connective tissue disease; and systemic lupus erythematosus. Orthologous to human SNRPC (small nuclear ribonucleoprotein polypeptide C).
