Enables actin binding activity; protein phosphatase 1 binding activity; and protein phosphatase activator activity. Involved in several processes, including enteric nervous system development; morphogenesis of embryonic epithelium; and negative regulation of integrin-mediated signaling pathway. Located in lamellipodium. Is expressed in central nervous system and retina. Orthologous to human PHACTR4 (phosphatase and actin regulator 4). [provided by Alliance of Genome Resources, Apr 2022]
