Retinol binding protein 4 RBP4 RBP is a 21kDa secreted protein, a member of the lipocalin family and is known as the primary transporter of retinol vitamin A to tissues. A recent report revealed RBP4 as an adipokine linking glucose transporter 4 GLUT4 suppression in adipose tissue to insulin. Elevated human and mouse serum RBP4 levels are associated with insulin resistance and its severity, obesity, and certain components of metabolic syndrome. Furthermore, human serum RBP4 levels are closely related to renal function.
