IGF-1 LR3, also known as Long Arg3 Insulin-like Growth Factor-1, is a synthetic peptide with significant importance in scientific research due to its unique properties and potential applications. IGF-1 LR3 is a modified version of the naturally occurring insulin-like growth factor-1 (IGF-1), with an extended half-life and enhanced bioactivity. This overview will delve into the structural composition, mechanism of action, and key research areas associated with IGF-1 LR3.

Structural Composition and Mechanism of Action

IGF-1 LR3 is a polypeptide consisting of 83 amino acids, which includes an alteration of the original IGF-1 sequence where arginine is substituted for glutamic acid at position 3. This modification, along with a 13-amino acid extension, significantly increases its stability and bioactivity compared to native IGF-1.

The primary mechanism of action for IGF-1 LR3 involves its interaction with the IGF-1 receptor (IGF-1R). Upon binding to IGF-1R, IGF-1 LR3 activates intracellular signaling pathways that are crucial for various cellular processes, including growth, development, and metabolism. These pathways include the PI3K-AKT and MAPK pathways, which play pivotal roles in cell proliferation, differentiation, and survival.
