Predicted to enable protein phosphatase regulator activity. Predicted to be involved in apoptotic process involved in morphogenesis; positive regulation of extrinsic apoptotic signaling pathway in absence of ligand; and protein dephosphorylation. Is active in glutamatergic synapse. Is expressed in several structures, including cerebral cortex; eye; genitourinary system; thymus primordium; and tooth. Orthologous to human PPP2R1B (protein phosphatase 2 scaffold subunit Abeta). [provided by Alliance of Genome Resources, Apr 2022]
