Enables cytoskeletal anchor activity; cytoskeletal protein binding activity; and ionotropic glutamate receptor binding activity. Involved in several processes, including axo-dendritic protein transport; learning or memory; and negative regulation of protein localization to microtubule. Acts upstream of or within photoreceptor cell maintenance and sensory perception of sound. Located in several cellular components, including axon initial segment; dendritic microtubule; and photoreceptor outer segment. Is expressed in cerebral cortex marginal zone; cortical plate; cortical subplate; and spinal cord. Orthologous to human MAP1A (microtubule associated protein 1A).
