ABSTRACT:
The present invention relates to providing novel therapeutics for treating diabetes other glycemic disorders. Such therapeutics involve the signaling pathways that contribute to regulation of glucose-stimulated insulin secretion. Of particular interest are modulators of a key component in the glucokinase pathway. Thus, the present provides methods of screening for modulators of glucokinase activity, expression, translocation, conformation, nitrosylation and interaction with other molecules as useful target for pharmacological manipulation in the treatment of diabetes and other glycemic disorders.
