    Summary
    Predicted to enable transmembrane transporter activity. Involved in regulation of presynaptic cytosolic calcium ion concentration and regulation of synaptic vesicle exocytosis. Located in synaptic vesicle. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human SV2B (synaptic vesicle glycoprotein 2B). [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.
