Predicted to enable myosin phosphatase regulator activity and protein phosphatase 1 binding activity. Predicted to be involved in several processes, including establishment of endothelial barrier; positive regulation of blood vessel endothelial cell proliferation involved in sprouting angiogenesis; and regulation of protein dephosphorylation. Predicted to be located in cell projection; nuclear speck; and perinuclear region of cytoplasm. Predicted to be active in plasma membrane. Orthologous to human PPP1R16B (protein phosphatase 1 regulatory subunit 16B). [provided by Alliance of Genome Resources, Apr 2022]
