Predicted to enable actin filament binding activity. Acts upstream of or within positive regulation of transcription by RNA polymerase II. Located in glutamatergic synapse. Is active in synapse. Is expressed in several structures, including central nervous system; heart; neural retina; skeletal muscle tissue; and trigeminal nerve. Orthologous to human ABLIM3 (actin binding LIM protein family member 3). [provided by Alliance of Genome Resources, Apr 2022]
