Importantly, it will be of significance to determine whether ROCK2, PKCβ2, PDK-1 and AKT also form a signaling complex as a mechanism to regulate GLUT4 translocation in adipose tissues and skeletal muscle in type 2 diabetes, since it is well-established that the translocation of GLUT4 to the membrane is the rate-limiting step in insulin-induced glucose sensitivity through activation of AKT in human patients, yet the detailed mechanisms remain elusive [51]. The gene discussed is AKT1; the disease is type 2 diabetes mellitus.
