General annotation (Comments)
| Function | 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: the PI3K-AKT/PKB pathway and the Ras-MAPK pathway. The result of activating the MAPK pathway is increased cellular proliferation, whereas activating the PI3K pathway inhibits apoptosis and stimulates protein synthesis. Phosphorylated IRS1 can activate the 85 kDa regulatory subunit of PI3K (PIK3R1), leading to activation of several downstream substrates, including protein AKT/PKB. AKT phosphorylation, in turn, enhances protein synthesis through mTOR activation and triggers the antiapoptotic effects of IGFIR through phosphorylation and inactivation of BAD. In parallel to PI3K-driven signaling, recruitment of Grb2/SOS by phosphorylated IRS1 or Shc leads to recruitment of Ras and activation of the ras-MAPK pathway. In addition to these two main signaling pathways IGF1R signals also through the Janus kinase/signal transducer and activator of transcription pathway (JAK/STAT). Phosphorylation of JAK proteins can lead to phosphorylation/activation of signal transducers and activators of transcription (STAT) proteins. In particular activation of STAT3, may be essential for the transforming activity of IGF1R. The JAK/STAT pathway activates gene transcription and may be responsible for the transforming activity. JNK kinases can also be activated by the IGF1R. IGF1 exerts inhibiting activities on JNK activation via phosphorylation and inhibition of MAP3K5/ASK1, which is able to directly associate with the IGF1R By similarity. When present in a hybrid receptor with INSR, binds IGF1 By similarity. |
| Catalytic activity | ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. |
| Enzyme regulation | Activated by autophosphorylation at Tyr-1163, Tyr-1167 and Tyr-1168 on the kinase activation loop; phosphorylation at all three tyrosine residues is required for optimal kinase activity. Inhibited by MSC1609119A-1, BMS-754807, PQIP, benzimidazole pyridinone, isoquinolinedione, bis-azaindole, 3-cyanoquinoline, 2,4-bis-arylamino-1,3-pyrimidine, pyrrolopyrimidine, pyrrole-5-carboxaldehyde, picropodophyllin (PPP), tyrphostin derivatives. While most inhibitors bind to the ATP binding pocket, MSC1609119A-1 functions as allosteric inhibitor and binds close to the DFG motif and the activation loop By similarity. Ref.5 |
| Subcellular location | |
| Post-translational modification | Autophosphorylated on tyrosine residues in response to ligand binding. Autophosphorylation occurs in trans, i.e. one subunit of the dimeric receptor phosphorylates tyrosine residues on the other subunit. Autophosphorylation occurs in a sequential manner; Tyr-1167 is predominantly phosphorylated first, followed by phosphorylation of Tyr-1163 and Tyr-1168. While every single phosphorylation increases kinase activity, all three tyrosine residues in the kinase activation loop (Tyr-1163, Tyr-1167 and Tyr-1168) have to be phosphorylated for optimal activity. Can be autophosphorylated at additional tyrosine residues (in vitro). Autophosphorylated is followed by phosphorylation of juxtamembrane tyrosines and C-terminal serines. Phosphorylation of Tyr-981 is required for IRS1- and SHC1-binding By similarity. Dephosphorylated by PTPN1. Polyubiquitinated at Lys-1170 and Lys-1173 through both 'Lys-48' and 'Lys-29' linkages, promoting receptor endocytosis and subsequent degradation by the proteasome. Ubiquitination is facilitated by pre-existing phosphorylation By similarity. |
| Disruption phenotype | Deficient mice are 45% of the size of wild-type littermates at birth, and die shortly due to severe organ hypoplasia. Ref.4 |
| Sequence similarities | Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily. Contains 3 fibronectin type-III domains. Contains 1 protein kinase domain. |
