Supplementary information

The IGF1 Receptor often referred to as IGF-1R is a transmembrane receptor protein composed of alpha and beta subunits. Studies indicate that the IGF1R protein is involved in mediating the effects of insulin-like growth factor 1 (IGF-1) and plays an important role in cellular signaling. It has a molecular weight of approximately 180 kDa and is widely expressed in various tissues with high concentrations in the liver muscle and brain. Being a tyrosine kinase receptor IGF1R plays an essential role in growth and metabolism.
Biological function summary

IGF1R contributes to several cellular processes including cell proliferation differentiation and survival. This receptor forms a complex upon ligand binding and undergoes autophosphorylation to activate intracellular signaling cascades. IGF1R activation recruits and phosphorylates insulin receptor substrates enabling the downstream signaling pathways that promote cell growth and survival. Its function in cellular responses makes it a focal point in understanding cell biology.

Pathways

IGF1R holds a central position in the PI3K/AKT and MAPK signaling cascades. These pathways play significant roles in cellular growth proliferation and survival. IGF1R phosphorylates various downstream effectors such as IRS-1 and Shc linking it to the activation of AKT and ERK respectively. Therefore it shares pathways with related proteins like the insulin receptor highlighting its importance in mediating similar biological responses.

IGF1R has been implicated in cancers and diabetes. Overexpression of IGF1R has been observed in various malignancies including breast cancer where it relates to resistance in treatment and poor prognosis with cell lines like MCF-7 often being studied in this context. Additionally disruptions in IGF1R signaling link to insulin resistance an important feature of type 2 diabetes. These connections make IGF1R a potential therapeutic target with IGF1R inhibitors currently under exploration to address these health challenges.

Target data

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.. When present in a hybrid receptor with INSR, binds IGF1. PubMed : 12138094 shows that hybrid receptors composed of IGF1R and INSR isoform Long are activated with a high affinity by IGF1, with low affinity by IGF2 and not significantly activated by insulin, and that hybrid receptors composed of IGF1R and INSR isoform Short are activated by IGF1, IGF2 and insulin. In contrast, PubMed : 16831875 shows that hybrid receptors composed of IGF1R and INSR isoform Long and hybrid receptors composed of IGF1R and INSR isoform Short have similar binding characteristics, both bind IGF1 and have a low affinity for insulin.
