Autoantibodies to the insulin receptor activate glycogen synthase in rat adipocytes. 1978

J C Lawrence, and J Larner, and C R Kahn, and J Roth

Autoantibodies to the insulin receptor mimic the effects of insulin on glycogen synthase and phosphorylase. The interaction of antibodies with adipocyte cell surface insulin receptors seems sufficient to promote stable changes in the activities of these intracellular enzymes, suggesting that internalization or processing of insulin is not important in the generation of these biological responses.

D007330	Insulin Antibodies	Antibodies specific to INSULIN.	Antibodies, Insulin
D007518	Isoantibodies	Antibodies from an individual that react with ISOANTIGENS of another individual of the same species.	Alloantibodies
D007527	Isoenzymes	Structurally related forms of an enzyme. Each isoenzyme has the same mechanism and classification, but differs in its chemical, physical, or immunological characteristics.	Alloenzyme,Allozyme,Isoenzyme,Isozyme,Isozymes,Alloenzymes,Allozymes
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D011972	Receptor, Insulin	A cell surface receptor for INSULIN. It comprises a tetramer of two alpha and two beta subunits which are derived from cleavage of a single precursor protein. The receptor contains an intrinsic TYROSINE KINASE domain that is located within the beta subunit. Activation of the receptor by INSULIN results in numerous metabolic changes including increased uptake of GLUCOSE into the liver, muscle, and ADIPOSE TISSUE.

D000273	Adipose Tissue	Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
