Testing Data

(Proximity Ligation Analysis (PLA) of protein-protein interactions between IGF1R and PIK3R3 HeLa cells were stained with IGF1R rabbit purified polyclonal 1:1200 and PIK3R3 mouse monoclonal antibody 1:50. Signals were detected by Duolink 30 Detection (red), and nuclei were counterstained with DAPI (blue). Each red dot represents the detection of protein-protein interaction complex.)

Related Product Information for anti-IGF1R antibody

IGF-1R is a heterotetrameric transmembrane receptor tyrosine kinase (RTK), responsible for mediating IGF bioactivity. The gene encoding for IGF-1R is located on chromosome 15q26 and encodes a single polypeptide of 1367aa that is constitutively expressed in most cells. IGF-1R contains two extracellular ligand binding alpha-subunits and two transmembrane beta-subunits. The beta-subunits possess tyrosine kinase catalytic domains that are activated upon ligand binding. Overexpression of the protein results in loss of tumor suppressors, including wild-type p53, BRCA1 and VHL. IGF-1R activation leads to autophosphorylation on tyrosines 1131, 1135 and 1136 in the kinase domain, followed by phosphorylation of juxtamembrane tyrosines and carboxy-terminal serines. This is followed by recruitment of specific docking intermediates, including insulin-receptor substrate-1 (IRS-1), Shc and 14-3-3 proteins. These molecules link IGF-1R to diverse signaling pathways, allowing induction of growth, transformation, differentiation and protection against apoptosis.

NCBI Description

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.

Uniprot Description

IGF1R: a receptor tyrosine kinase that binds insulin-like growth factor 1 (IGF1) with a high affinity and IGF2 with a lower affinity. Functions as an anti-apoptotic agent by enhancing cell survival. Can play a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. 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. Mutated in rare cases of pre- and post-natal growth retardation. One SNP associated with increased human longevity. Increased expression of IGF1R and other pathway members associated with progression and malignancy in a range of cancers. Inhibitors: AG1024, AEW541.
