    Summary
    A structural constituent of presynaptic active zone. Involved in regulation of calcium-dependent activation of synaptic vesicle fusion; regulation of presynaptic cytosolic calcium ion concentration; and synaptic vesicle priming. Located in synapse. Is active in GABA-ergic synapse; glutamatergic synapse; and presynaptic active zone cytoplasmic component. Is expressed in several structures, including central nervous system; gut; peripheral nervous system ganglion; sensory organ; and urinary system. Orthologous to human ERC2 (ELKS/RAB6-interacting/CAST family member 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.
