Summary: 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 regulation of protein localization. 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 postsynaptic density. Is expressed in cerebral cortex marginal zone; cortical plate; cortical subplate; and spinal cord. Orthologous to human MAP1A (microtubule associated protein 1A).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
