Predicted to enable protein C-terminus binding activity and protein serine/threonine phosphatase activity. Acts upstream of or within several processes, including apoptotic mitochondrial changes; proteasome-mediated ubiquitin-dependent protein catabolic process; and response to hydrogen peroxide. Located in cytoplasm. Part of protein phosphatase type 2A complex. Is expressed in several structures, including cardiovascular system; eye; genitourinary system; gut; and nervous system. Orthologous to human PPP2CB (protein phosphatase 2 catalytic subunit beta). [provided by Alliance of Genome Resources, Apr 2022]
