Description
|
IR is a receptor tyrosine kinase which mediates the biological activities of insulin by regulating multiple signaling pathways through activation of a series of phosphorylation cascades. The receptor is a disulfide linked heterotetrameric glycoprotein consisting of two alpha subunits and two beta subunits arranged in the following configuration: beta-alpha-alpha-beta. The alpha subunits each contain insulin binding sites and are entirely extracellular in localization. The beta subunits each possess an extracellular domain, a single transmembrane domain, and a cytoplasmic tyrosine kinase domain. Binding of insulin to the alpha subunits induces a conformation change in the receptor which activates the kinase domain, stimulating tyrosine autophosphorylation of the receptor and tyrosine phosphorylation of at least five different insulin receptor substrates designated IRS-1-4, and Shc.

Specificity
|
This antibody is specific for the approximately 95 kDa IR and shows no cross-reactivity with insulin like growth factor (IGF) receptors. Phosphorylation of the threonine residue within this sequence (corresponding to threonine 1348) decreases the affinity
