Predicted to enable several functions, including AP-2 adaptor complex binding activity; phosphatidylinositol phosphate binding activity; and protein dimerization activity. Involved in endocytosis; presynaptic modulation of chemical synaptic transmission; and regulation of receptor-mediated endocytosis. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Is expressed in several structures, including brain; heart; and testis. Orthologous to human HIP1 (huntingtin interacting protein 1).
