Disruption of Disulfide Bonds of Insulin Receptor as a Cause of Insulin Resistance in DM2 | Chapter 04 | Recent Advances in Biological Research Vol. 1
Many theories have been put forward to
explain insulin resistance in DM2. The cause of insulin resistance still
remained an enigma till date. Defect in insulin signaling pathway is one such
possibility considered for insulin resistance in DM2. For insulin signal
transduction to occur downstream, the insulin receptor should be in tetrameric,
holo-enzyme form so that the conformational changes and auto-phosphorylation
steps take place. A prerequisite to this is, linkage of the two α-sub-units and
α,β -sub-units of the pair of the dimers by disulfide bonds. Without this, the
receptor is in the α,β dimer half-enzyme form, devoid of any binding affinity
to the ligand or auto- phosphorylating activity. The article intends to
explore, disruption of the disulfide bond formation of the insulin receptor as
a possible cause of insulin resistance in DM2.
