ATP-sensitive K{sup +} (KATP) channels play a crucial role in coupling metabolic energy to the membrane potential of cells. Recently, we have isolated a KATP channel cDNA (uK{sub ATP}-1) that is expressed ubiquitously in rat tissues including pancreatic islets, pituitary, skeletal muscle, and heart. Here, we report cloning of the human cDNA and gene encoding uK{sub ATP}-1. Human uK{sub ATP}-1 is a protein of 424 amino acids exhibiting 98% identity with rat uK{sub ATP}-1. The human gene encoding uK{sub ATP}-1, designated KCNJ8, is approximately 9.7 kb in length and is composed of three exons. KCNJ8 was mapped to chromosome 12p11.23 using fluorescence in situ hybridization. 14 refs., 2 figs., 1 tab.
