What is the Meaning of Insulin Signaling?

Insulin signaling refers to the intricate molecular cascade initiated when the hormone insulin binds to its transmembrane receptor, initiating a process critical for cellular glucose utilization and energy storage. This pathway dictates how peripheral tissues, notably muscle and adipose cells, respond to circulating glucose levels. Proper signaling is the cornerstone of glycemic control.

What is the Origin of Insulin Signaling?

The term describes the sequence of events—the signal transmission—that occurs after insulin, the pancreatic hormone, docks with its specific cellular receptor. Its scientific delineation has been pivotal in understanding the pathogenesis of Type 2 Diabetes Mellitus.

What is the Mechanism of Insulin Signaling?

Insulin binding activates the receptor's intrinsic tyrosine kinase activity, leading to autophosphorylation and subsequent phosphorylation of intracellular substrates, such as $text{IRS}$ proteins. This activation cascade ultimately recruits $text{GLUT}4$ glucose transporters to the plasma membrane in muscle and fat cells, enabling glucose influx. Impairment at any step in this phosphorylation sequence results in insulin resistance.
