Enables actin binding activity. Involved in actin cytoskeleton organization; nervous system development; and regulation of neuron migration. Located in cytosol and nucleus. Is expressed in several structures, including central nervous system and neural retina. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 70. Orthologous to human PHACTR1 (phosphatase and actin regulator 1). [provided by Alliance of Genome Resources, Apr 2022]
