Enables mRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome; nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; and regulation of alternative mRNA splicing, via spliceosome. Located in nucleus. Is expressed in several structures, including central nervous system; future brain; and olfactory epithelium. Human ortholog(s) of this gene implicated in thrombocytopenia-absent radius syndrome. Orthologous to human RBM8A (RNA binding motif protein 8A). [provided by Alliance of Genome Resources, Apr 2022]
