Summary: Enables ADP binding activity and ATP binding activity. Involved in negative regulation of insulin secretion and positive regulation of insulin secretion involved in cellular response to glucose stimulus. Acts upstream of or within several processes, including action potential; glutamate secretion, neurotransmission; and neuromuscular process. Part of protein-containing complex. Is active in plasma membrane. Is expressed in cerebral cortex; foregut-midgut junction; heart ventricle; and retina inner nuclear layer. Used to study hyperinsulinemic hypoglycemia and transient neonatal diabetes mellitus. Human ortholog(s) of this gene implicated in glucose metabolism disease (multiple) and hypertension. Orthologous to human ABCC8 (ATP binding cassette subfamily C member 8). [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.
