Alteration in phosphorylation of P20 is associated with insulin resistance.

Abstract

We have recently identified a small phosphoprotein, P20, as a common intracellular target for insulin and several of its antagonists, including amylin, epinephrine, and calcitonin gene-related peptide. These hormones elicit phosphorylation of P20 at its different sites, producing three phosphorylated isoforms: S1 with an isoelectric point (pI) value of 6.0… (More)
