Predicted to enable identical protein binding activity and miRNA binding activity. Acts upstream of or within negative regulation of RNA metabolic process; negative regulation of cell population proliferation; and positive regulation of smooth muscle cell apoptotic process. Predicted to be located in nuclear speck. Predicted to be part of protein-containing complex. Predicted to be active in nucleus. Is expressed in several structures, including branchial arch; central nervous system; early conceptus; oocyte; and sensory organ. Human ortholog(s) of this gene implicated in TARP syndrome. Orthologous to human RBM10 (RNA binding motif protein 10). [provided by Alliance of Genome Resources, Apr 2022]
