The insulin R/CD220 protein is a receptor tyrosine kinase that coordinates insulin action by phosphorylating substrates such as IRS and SHC upon insulin binding. Phosphorylated IRS activates PI3K-AKT/PKB to exert metabolic effects, and activates Ras-MAPK to promote growth and differentiation. Insulin R/CD220 Protein, Human (sf9, His-GST) is the recombinant human-derived Insulin R/CD220 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag.

Human

The Insulin R/CD220 protein, a receptor tyrosine kinase, orchestrates the diverse actions of insulin through the phosphorylation of multiple intracellular substrates upon insulin binding. These substrates include insulin receptor substrates (IRS1, 2, 3, 4), SHC, GAB1, CBL, and other signaling intermediates. Phosphorylated IRS proteins activate two main signaling pathways: the PI3K-AKT/PKB pathway, pivotal for insulin's metabolic effects, and the Ras-MAPK pathway, which collaborates with PI3K to regulate cell growth and differentiation. The PI3K-AKT/PKB pathway triggers the translocation of the glucose transporter SLC2A4/GLUT4 to the cell membrane, facilitating glucose transport. Activated AKT/PKB, a downstream effector, induces an anti-apoptotic effect by phosphorylating BAD, regulates the expression of metabolic enzymes, and modulates the mTORC1 signaling pathway, integrating insulin signals for cell growth and metabolism. The Ras/RAF/MAP2K/MAPK pathway mediates insulin-induced cell growth, survival, and cellular differentiation. In addition to insulin, the receptor can bind insulin-like growth factors (IGFI and IGFII). Hybrid receptors composed of IGF1R and INSR isoforms exhibit varying affinities for IGFs and insulin, influencing their activation patterns. Furthermore, in adipocytes, the receptor inhibits lipolysis.
