Is an ortholog of human RBPMS (RNA binding protein, mRNA processing factor) and RBPMS2 (RNA binding protein, mRNA processing factor 2). Is predicted to have snRNA stem-loop binding activity. Is involved in several processes, including embryo development\; hemidesmosome assembly\; and mechanosensory behavior. Localizes to the nucleus. Is expressed in the embryonic cell\; the epithelial system\; the head\; the nervous system\; and the vulva.
