CC   -!- FUNCTION: Receptor tyrosine kinase which mediates actions of insulin-
CC       like growth factor 1 (IGF1). Binds IGF1 with high affinity and IGF2 and
CC       insulin (INS) with a lower affinity. The activated IGF1R is involved in
CC       cell growth and survival control. IGF1R is crucial for tumor
CC       transformation and survival of malignant cell. Ligand binding activates
CC       the receptor kinase, leading to receptor autophosphorylation, and
CC       tyrosines phosphorylation of multiple substrates, that function as
CC       signaling adapter proteins including, the insulin-receptor substrates
CC       (IRS1/2), Shc and 14-3-3 proteins. Phosphorylation of IRSs proteins
CC       lead to the activation of two main signaling pathways: the PI3K-AKT/PKB
CC       pathway and the Ras-MAPK pathway. The result of activating the MAPK
CC       pathway is increased cellular proliferation, whereas activating the
CC       PI3K pathway inhibits apoptosis and stimulates protein synthesis.
CC       Phosphorylated IRS1 can activate the 85 kDa regulatory subunit of PI3K
CC       (PIK3R1), leading to activation of several downstream substrates,
CC       including protein AKT/PKB. AKT phosphorylation, in turn, enhances
CC       protein synthesis through mTOR activation and triggers the
CC       antiapoptotic effects of IGFIR through phosphorylation and inactivation
CC       of BAD. In parallel to PI3K-driven signaling, recruitment of Grb2/SOS
CC       by phosphorylated IRS1 or Shc leads to recruitment of Ras and
CC       activation of the ras-MAPK pathway. In addition to these two main
CC       signaling pathways IGF1R signals also through the Janus kinase/signal
CC       transducer and activator of transcription pathway (JAK/STAT).
CC       Phosphorylation of JAK proteins can lead to phosphorylation/activation
CC       of signal transducers and activators of transcription (STAT) proteins.
CC       In particular activation of STAT3, may be essential for the
CC       transforming activity of IGF1R. The JAK/STAT pathway activates gene
CC       transcription and may be responsible for the transforming activity. JNK
CC       kinases can also be activated by the IGF1R. IGF1 exerts inhibiting
CC       activities on JNK activation via phosphorylation and inhibition of
CC       MAP3K5/ASK1, which is able to directly associate with the IGF1R (By
CC       similarity). When present in a hybrid receptor with INSR, binds IGF1
CC       (By similarity). {ECO:0000250}.

CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU10028};
CC   -!- ACTIVITY REGULATION: Activated by autophosphorylation at Tyr-434, Tyr-
CC       438 and Tyr-439 on the kinase activation loop; phosphorylation at all
CC       three tyrosine residues is required for optimal kinase activity.
CC       Inhibited by MSC1609119A-1, BMS-754807, PQIP, benzimidazole pyridinone,
CC       isoquinolinedione, bis-azaindole, 3-cyanoquinoline, 2,4-bis-arylamino-
CC       1,3-pyrimidine, pyrrolopyrimidine, pyrrole-5-carboxaldehyde,
CC       picropodophyllin (PPP), tyrphostin derivatives. While most inhibitors
CC       bind to the ATP binding pocket, MSC1609119A-1 functions as allosteric
CC       inhibitor and binds close to the DFG motif and the activation loop (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Tetramer of 2 alpha and 2 beta chains linked by disulfide
CC       bonds. The alpha chains contribute to the formation of the ligand-
CC       binding domain, while the beta chain carries the kinase domain.
CC       Interacts with PIK3R1 and with the PTB/PID domains of IRS1 and SHC1 in
CC       vitro when autophosphorylated on tyrosine residues. Forms a hybrid
CC       receptor with INSR, the hybrid is a tetramer consisting of 1 alpha
CC       chain and 1 beta chain of INSR and 1 alpha chain and 1 beta chain of
CC       IGF1R. Interacts with ARRB1 and ARRB2. Interacts with GRB10. Interacts
CC       with RACK1 (By similarity). Interacts with SOCS1, SOCS2 and SOCS3 (By
CC       similarity). Interacts with 14-3-3 proteins (By similarity). Interacts
CC       with NMD2 (By similarity). Interacts with MAP3K5 (By similarity).
CC       Interacts with STAT3 (By similarity). Interacts (nascent precursor
CC       form) with ZFAND2B (By similarity). {ECO:0000250,
CC       ECO:0000250|UniProtKB:P08069}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass type I
CC       membrane protein {ECO:0000250}.
CC   -!- PTM: Autophosphorylated on tyrosine residues in response to ligand
CC       binding. Autophosphorylation occurs in trans, i.e. one subunit of the
CC       dimeric receptor phosphorylates tyrosine residues on the other subunit.
CC       Autophosphorylation occurs in a sequential manner; Tyr-438 is
CC       predominantly phosphorylated first, followed by phosphorylation of Tyr-
CC       434 and Tyr-439. While every single phosphorylation increases kinase
CC       activity, all three tyrosine residues in the kinase activation loop
CC       (Tyr-438, Tyr-434 and Tyr-439) have to be phosphorylated for optimal
CC       activity. Can be autophosphorylated at additional tyrosine residues (in
CC       vitro). Autophosphorylated is followed by phosphorylation of
CC       juxtamembrane tyrosines and C-terminal serines. Phosphorylation of Tyr-
CC       253 is required for IRS1- and SHC1-binding (By similarity).
CC       Phosphorylation of Ser-551 by GSK-3beta restrains kinase activity and
CC       promotes cell surface expression, it requires a priming phosphorylation
CC       at Ser-555. Dephosphorylated by PTPN1 (By similarity). {ECO:0000250}.
CC   -!- PTM: Polyubiquitinated at Lys-441 and Lys-444 through both 'Lys-48' and
CC       'Lys-29' linkages, promoting receptor endocytosis and subsequent
CC       degradation by the proteasome. Ubiquitination is facilitated by pre-
CC       existing phosphorylation (By similarity). {ECO:0000250}.
CC   -!- PTM: Sumoylated with SUMO1. {ECO:0000250}.
CC   -!- PTM: Controlled by regulated intramembrane proteolysis (RIP). Undergoes
CC       metalloprotease-dependent constitutive ectodomain shedding to produce a
CC       membrane-anchored 52 kDa C-Terminal fragment which is further processed
CC       by presenilin gamma-secretase to yield an intracellular 50 kDa fragment
CC       (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC       kinase family. Insulin receptor subfamily. {ECO:0000255|PROSITE-
CC       ProRule:PRU00159}.
