Predicted to be involved in positive regulation of mRNA splicing, via spliceosome. Predicted to be part of spliceosomal complex. Orthologous to several human genes including RBMY1A1 (RNA binding motif protein Y-linked family 1 member A1); RBMY1B (RNA binding motif protein Y-linked family 1 member B); and RBMY1D (RNA binding motif protein Y-linked family 1 member D).
