Human receptor tyrosine kinases (RTKs)

Human receptor tyrosine kinases (RTKs) are a family of around 60 plasma
membrane receptors with intrinsic kinase activity. They play important roles in
transducing various types of signals from the extracellular environment to the cell interior.
One important example of these RTKs is the insulin receptor (INSR), which plays a
fundamental role in glucose metabolism. Write an essay in which you describe in detail
the structure, function, and regulation of INSR
