IGF1 Protein

IGF1 Protein

Insulin-like growth factor 1 (IGF-1) is a protein that in humans is encoded by the IGF1 gene. IGF-1 is produced throughout life: it plays an important role in childhood growth and continues to have anabolic effects in adults. The highest rates of IGF-1 production occur during the pubertal growth spurt. The lowest levels occur in infancy and old age.
