Enables PH domain binding activity and spectrin binding activity. Predicted to be involved in actomyosin structure organization and positive regulation of protein localization to cell cortex. Predicted to act upstream of or within actin cytoskeleton organization and regulation of cell shape. Predicted to be located in actin cytoskeleton; cell junction; and nucleoplasm. Predicted to be part of COP9 signalosome. Predicted to be active in cytoskeleton and plasma membrane. Is expressed in several structures, including bone; central nervous system; sensory organ; thymus; and urinary system. Orthologous to human EPB41L2 (erythrocyte membrane protein band 4.1 like 2).
