The receptor tyrosine kinase (RTK) pathway is carefully regulated by a variety of positive and negative feedback loops. [24] Because RTKs coordinate a wide variety of cellular functions such as cell proliferation and differentiation, they must be regulated to prevent severe abnormalities in cellular functioning such as cancer and fibrosis.
Many receptor enzymes have closely related structure and receptor tyrosine kinase activity, and it has been determined that the foundational or prototypical receptor enzyme is insulin. [2] Insulin receptor substrates IRS2 and IRS3 each have unique characteristic tissue function and distribution that serves to enhance signaling capabilities in ...
Tyrosine-protein kinase receptor UFO is a protein that in human is encoded by the AXL gene. [ 5 ] [ 6 ] The gene was initially designated as UFO, in allusion to the unidentified function of this protein. [ 7 ]
KIT is a cytokine receptor expressed on the surface of hematopoietic stem cells as well as other cell types. Altered forms of this receptor may be associated with some types of cancer. [9] KIT is a receptor tyrosine kinase type III, which binds to stem cell factor, also known as "steel factor" or "c-kit

The IGF-1 receptor seems to be the "physiologic" receptor—it binds IGF-1 at significantly higher affinity than it binds insulin. [9] Like the insulin receptor, the IGF-1 receptor is a receptor tyrosine kinase—meaning it signals by causing the addition of a phosphate molecule on particular tyrosines.
The kinase domain is vital for JAK activity, since it allows JAKs to phosphorylate (add phosphate groups to) proteins. There are seven STAT proteins: STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B and STAT6. [1] STAT proteins contain many different domains, each with a different function, of which the most conserved region is the SH2 domain. [2]
A receptor tyrosine kinase is a "tyrosine kinase" which is located at the cellular membrane, and is activated by binding of a ligand to the receptor's extracellular domain. Other examples of tyrosine kinase receptors include the insulin receptor, the IGF1 receptor, the MuSK protein receptor, the Vascular Endothelial Growth Factor (or VEGF ...
