Summary: Enables actin binding activity; collagen binding activity; and microtubule binding activity. A structural constituent of presynapse. Involved in negative regulation of microtubule depolymerization. Located in several cellular components, including axon; dendrite; and neuronal cell body. Part of microtubule associated complex. Is active in glutamatergic synapse; postsynaptic density; and presynaptic active zone. Biomarker of hypothyroidism. 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.
