Description
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. When present in a hybrid receptor with INSR, binds IGF1.Adams, T.E. et al. (2000) Cell. Mol. Life Sci. 57, 1050-1093Baserga, R. et al. (2000) Oncogene 19, 5574-5581Scheidegger, K.J. et al. (2000) J.

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous level of total IGF-1R protein.
Subcellular Location
Cell membrane, Single-pass type I membrane protein
Receptor tyrosine kinase which mediates actions of insulin-like growth factor 1 (IGF1). Binds IGF1 with high affinity and IGF2 and insulin (INS) with a lower affinity. The activated IGF1R is involved in cell growth and survival control. IGF1R is crucial for tumor transformation and survival of malignant cell. Ligand binding activates the receptor kinase, leading to receptor autophosphorylation, and tyrosines phosphorylation of multiple substrates, that function as signaling adapter proteins including, the insulin-receptor substrates (IRS1/2), Shc and 14-3-3 proteins. Phosphorylation of IRSs proteins lead to the activation of two main signaling pathways
Protein kinase superfamily, Tyr protein kinase family, Insulin receptor subfamily
Tissue Specificity
Found as a hybrid receptor with INSR in muscle, heart, kidney, adipose tissue, skeletal muscle, hepatoma, fibroblasts, spleen and placenta (at protein level). Expressed in a variety of tissues. Overexpressed in tumors, including melanomas, cancers of the
