Summary: Enables ATP hydrolysis activity; ionotropic glutamate receptor binding activity; and small GTPase binding activity. Involved in several processes, including cellular response to glycine; endosomal transport; and positive regulation of neurogenesis. Located in several cellular components, including dendritic spine; neuronal cell body; and recycling endosome. Is active in several cellular components, including Schaffer collateral - CA1 synapse; postsynaptic actin cytoskeleton; and postsynaptic recycling endosome membrane. Human ortholog(s) of this gene implicated in microvillus inclusion disease and progressive familial intrahepatic cholestasis. Orthologous to human MYO5B (myosin VB).

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.
