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.
Key Applications:
- Immunocytochemistry
- Immunoprecipitation
- Western Blotting
UniProt Summary:
FUNCTION: SwissProt: P08069 # 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.
SIZE: 1367 amino acids; 154793 Da
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). & Phosphorylation of Tyr-980 is required for IRS1- and SHC1- binding.
DISEASE: SwissProt: P08069 # 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: SwissProt: P08069 ## Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily. & Contains 3 fibronectin type-III domains. & Contains 1 protein kinase domain.
