The protein kinase B beta (AKT) pathway mediates insulin-stimulated glucose transport by increasing glucose transporter GLUT4 translocation from intracellular stores to the plasma membrane. C2 domain-containing protein 5 (C2CD5 aka C2 domain-containing phosphoprotein 138kDa) has been shown to be required for optimal insulin-stimulated GLUT4 translocation and fusion of GLUT4 vesicles with the plasma membrane in adipocytes. It is also able to bind Ca2+ and lipid membranes in its C2 domain. C2CD5 is a substrate for RAC-beta serine/threonine-protein kinase (AKT2), which phosphorylates C2CD5 at serine 197. Phosphorylated C2CD5 optimises GLUT4 translocation to the plasma membrane. The role of human C2CD5 is inferred from the role of the orthologous mouse protein (Xie et al. 2011).
