Predicted to enable identical protein binding activity and mRNA binding activity. Predicted to be involved in several processes, including mRNA processing; nervous system development; and regulation of RNA splicing. Predicted to act upstream of or within regulation of alternative mRNA splicing, via spliceosome and sensory perception of sound. Predicted to be located in nucleus. Orthologous to human SRRM4 (serine/arginine repetitive matrix 4). [provided by Alliance of Genome Resources, Apr 2022]
