Background
IRS-1 (Insulin receptor substrate-1) is a cytoplasmic adaptor of IRS protein family. It transduces downstream signals from insulin and IGF-1 receptors. Receptor-triggered tyrosine phosphorylation of IRS-1 recruits effectors including PI3K and initiates PI3K-AKT cascade to regulate glucose metabolism, cell proliferation and survival. Serine phosphorylation promotes IRS-1 turnover and signal desensitization, strongly linked to insulin resistance. Dysregulated IRS-1 signaling underlies metabolic disorders and tumor progression.
