Predicted to enable several functions, including clathrin binding activity; phosphatidylinositol phosphate binding activity; and protein dimerization activity. Involved in endocytosis and positive regulation of receptor-mediated endocytosis. Predicted to be located in Golgi apparatus and postsynapse. Predicted to be extrinsic component of cytoplasmic side of plasma membrane and extrinsic component of presynaptic membrane. Predicted to be active in clathrin-coated vesicle and presynapse. Predicted to be extrinsic component of postsynaptic membrane. Is expressed in brain; cerebral cortex; embryo; telencephalon; and testis. Orthologous to human HIP1 (huntingtin interacting protein 1).
