These data suggest that protein kinase C may regulate the function of the insulin receptor.

Protein kinase C (PKC) has been suggested as a mediator of insulin's effect on glucose transport, and PKC-mediated modulation of tyrosine kinase activity in the insulin receptor has been implicated in regulating the insulin sensitivity of tissues.

Furthermore, the increased PIP2-PLC in diabetic liver may result in: (a) increased intracellular concentrations of IP3 and thus increased Ca2+, which has been postulated to induce insulin resistance; and (b) increased diacylglycerol and thus increased protein kinase C which phosphorylates the insulin receptor at serine residues inactivating the insulin receptor kinase.

In this model system, activation of protein kinase C is shown to interfere with insulin receptor signalling by inhibiting tyrosine phosphorylation of IRS-1 and its subsequent binding by phosphatidylinositol 3-kinase.

This insulin resistance was associated with impaired insulin receptor substrate (IRS)-2-associated phosphatidylinositol 3' (PI3) kinase activation and IRS-2 tyrosine phosphorylation as well as significantly decreased protein kinase C (PKC)-zeta/lambda activation in response to insulin.
