    Protocol

    Specificity / Sensitivity

    Phospho-IGF-I Receptor β (Tyr980) (C14A11) Rabbit mAb detects endogenous levels of IGF-I β receptor protein when phosphorylated at Tyr980. The antibody may cross-react with activated insulin receptors and FLT3.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr980 of human IGF-I Receptor β.

    Background

    Type I insulin-like growth factor receptor (IGF-IR) is a transmembrane receptor tyrosine kinase that is widely expressed in many cell lines and cell types within fetal and postnatal tissues (1-3). Receptor autophosphorylation follows binding of the IGF-I and IGF-II ligands. Three tyrosine residues within the kinase domain (Tyr1131, Tyr1135, and Tyr1136) are the earliest major autophosphorylation sites (4). Phosphorylation of these three tyrosine residues is necessary for kinase activation (5,6). Insulin receptors (IRs) share significant structural and functional similarity with IGF-I receptors, including the presence of an equivalent tyrosine cluster (Tyr1146/1150/1151) within the kinase domain activation loop. Tyrosine autophosphorylation of IRs is one of the earliest cellular responses to insulin stimulation (7). Autophosphorylation begins with phosphorylation at Tyr1146 and either Tyr1150 or Tyr1151, while full kinase activation requires triple tyrosine phosphorylation (8).
    Tyr980 of IGF-IR appears to be important for receptor kinase activation. Located in the IGF-IR juxtamembrane region, phosphorylation of this tyrosine residue creates a docking site for the binding of downstream adaptor or docking proteins (9).
