These channels are composed of four subunits of SUR1 and four subunits of KIR6.2 encoded by the ABCC8 and KNCJ11 genes, respectively. Inactivating mutations in these two g...

PMID:31137773.Ion channels and transporters play essential roles in excitable cells, including cardiac, skeletal and smooth muscle cells, neurons, and endocrine cells. In pancreatic beta-cells, KATPchannels link the metabolic signals generated inside the cell to changes in the beta-cell membra...

PMID:32376986ATP-sensitive potassium (KATP) channels are composed of a pore-forming Kir6.2 potassium channel and a regulatory ABC transporter sulfonylurea receptor 1 (SUR1). This channel has a hetero-octameric structure compromising of four SUR1 subunits and four Ki...
