The ATP-sensitive potassium channel (KATP) regulates insulin secretion in pancreatic cells. regulator has been shown to partially overcome the trafficking defect of a cystic fibrosis transmembrane conductance regulator mutation, F508. We found that coexpression of F1388 SUR1AAA with Kir6.2 led to partial surface expression of the mutant channel. Moreover, mutant channels were active. Compared with… Continue reading The ATP-sensitive potassium channel (KATP) regulates insulin secretion in pancreatic cells.
