Predicted to enable C2H2 zinc finger domain binding activity; mRNA binding activity; and protein N-terminus binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in Cajal body and nuclear speck. Predicted to be part of U2-type catalytic step 2 spliceosome and U2-type precatalytic spliceosome. Orthologous to human SRRM2 (serine/arginine repetitive matrix 2). [provided by Alliance of Genome Resources, Apr 2022]
