Summary: Enables several functions, including nitric-oxide synthase binding activity; transmembrane transporter binding activity; and type 3 metabotropic glutamate receptor binding activity. Involved in several processes, including positive regulation of nitric-oxide synthase activity; regulation of calcium ion transmembrane transporter activity; and regulation of vesicle-mediated transport. Located in several cellular components, including growth cone; myelin sheath; and synaptic vesicle membrane. Is active in Schaffer collateral - CA1 synapse; postsynaptic cytosol; and presynaptic cytosol. Biomarker of type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in catecholaminergic polymorphic ventricular tachycardia 4 and long QT syndrome 14. Orthologous to human CALM1 (calmodulin 1).

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.
