    Summary
    Enables GABA receptor binding activity and myosin binding activity. Involved in exocytosis. Located in several cellular components, including axonemal microtubule; symmetric synapse; and trans-Golgi network. Is active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and postsynapse. Human ortholog(s) of this gene implicated in periventricular nodular heterotopia. Orthologous to human ARFGEF2 (ADP ribosylation factor guanine nucleotide exchange factor 2). [provided by Alliance of Genome Resources, Dec 2024]

    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.
