Predicted to enable several functions, including 14-3-3 protein binding activity; phosphatase regulator activity; and protein kinase binding activity. Acts upstream of or within cellular response to xenobiotic stimulus; protein dephosphorylation; and regulation of nucleocytoplasmic transport. Located in A band and Z disc. Is expressed in corpus striatum; genital tubercle epithelium; head mesenchyme; urethra epithelium; and urothelium. Orthologous to human PPP1R12A (protein phosphatase 1 regulatory subunit 12A).
