Summary: Enables protein kinase binding activity. Involved in synaptic vesicle priming. Acts upstream of or within intracellular calcium ion homeostasis. Located in cell-cell junction; neuromuscular junction; and synaptic vesicle. Is active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and presynaptic active zone. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy. Orthologous to human SV2A (synaptic vesicle glycoprotein 2A).

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.
