Predicted to enable U12 snRNA binding activity and pre-mRNA intronic binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in nucleoplasm. Predicted to be part of U12-type spliceosomal complex. Is expressed in central nervous system; dorsal root ganglion; nose; and trigeminal nerve. Human ortholog(s) of this gene implicated in isolated growth hormone deficiency. Orthologous to human RNPC3 (RNA binding region (RNP1, RRM) containing 3).
