ABSTRACT:
The present invention describes modulator of protein kinase B (PKB)/Akt proteins, exemplified by the Tribbles (TRB) family. An exemplary member of the TRB family, TRB-3, binds to Akt and inhibits its catalytic activity, in turn causing altered regulation of glucose metabolism pathways. TRB-3 expression is strongly induced in the fasting state, and upregulated in mouse models of type II, causing disruptions in insulin signaling. Accordingly, the present invention further provides compositions and methods for disrupting the interaction between such a modulator and PKB/Akt protein kinases. Also provided are methods of determining if a subject has a predisposition to impaired glucose regulation and methods for treating diabetes mellitus using invention compositions.
