It shows no cross-reaction with insulin receptor. Its epitope localizes between a.a. 1323-1337 of IGF-1R. Both IGF-1R and insulin receptor are synthesized as a single polypeptide which is glycosylated and proteolytically cleaved to give the α- and β-subunits, which are disulfide-linked in a β-α-α-β configuration in the mature receptor. The α-subunit is completely extracellular, while the β-subunit spans membrane.

View All» Clone: 1-2 View All» Isotype: IgG2b View All» Background Information: IGF-I and -II signal through the IGF-I Receptor, which is homologous to the Insulin Receptor. The high-affinity IGF-II Receptor does not play a direct role in signaling, but regulates the concentration of free IGF-II. The IGFs are involved in skeletal growth, and are essential for prevention of apoptosis. Serum levels of free IGFs are kept low by the action of IGF binding proteins (IGFBPs), which sequester the IGFs. Overexpression of IGFBPs may induce apoptosis, presumably by reduction of free IGF; IGFBP levels are also altered in some cancers. The IGF-I Receptor is not as mitogenic as some other growth factor receptors, but its ability to activate the PI3 Kinase pathway, through the Insulin Receptor Substrate (IRS) proteins, is critical for mediating cell survival.

      View All» Entrez Gene Summary: This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival. [provided by RefSeq] View All» UniProt Summary: FUNCTION: This receptor binds insulin-like growth factor 1 (IGF1) with a high affinity and IGF2 with a lower affinity. It has a tyrosine-protein kinase activity, which is necessary for the activation of the IGF1-stimulated downstream signaling cascade. CATALYTIC ACTIVITY: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. ENZYME REGULATION: Autophosphorylation activates the kinase activity. SUBUNIT: Tetramer of 2 alpha and 2 beta chains linked by disulfide bonds. The alpha chains contribute to the formation of the ligand-binding domain, while the beta chain carries the kinase domain. Interacts with PIK3R1 and with the PTB/PID domains of IRS1 and SHC1 in vitro when autophosphorylated on tyrosine residues. SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein. TISSUE SPECIFICITY: Expressed in a variety of tissues. PTM: The cytoplasmic domain of the beta subunit is autophosphorylated on tyrosine residues in response to insulin-like growth factor I (IGF I). PTM: Phosphorylation of Tyr-980 is required for IRS1- and SHC1-binding. DISEASE: Defects in IGF1R may be a cause in some cases of resistance to insulin-like growth factor 1 (IGF1 resistance) [MIM:270450]. IGF1 resistance is a gowth deficiency disorder characterized by intrauterine growth retardation and poor postnatal growth accompanied with increased plasma IGF1. SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily. SIMILARITY: Contains 3 fibronectin type-III domains. SIMILARITY: Contains 1 protein kinase domain.
