Insulin-like Growth Factor 1 (IGF1)

Target
IGF1
Molecular classification
Peptidic hormone, Growth factor
01

Overview

Insulin-like growth factor 1 (IGF-1) is a protein that acts as the main mediator of growth hormone (GH) effects. It stimulates systemic body growth, particularly in skeletal muscle, cartilage, and bone. IGF-1 exerts its biological actions primarily by binding to the type I insulin-like growth factor receptor (IGF-1R), activating intracellular signaling cascades. It is essential for fetal development and maintains tissue homeostasis in adults. Dysregulation is associated with diseases like cancer and muscle disorders.
