The IRS-1 (Phospho-Ser323) antibody is a specialized tool used to detect phosphorylation of insulin receptor substrate-1 (IRS-1) at serine residue 323. a post-translational modification critical for regulating insulin signaling. IRS-1 is a key adaptor protein in insulin and insulin-like growth factor (IGF) pathways, mediating downstream signaling through interactions with phosphatidylinositol 3-kinase (PI3K) and other effectors. Phosphorylation at Ser323. often induced by stress-activated kinases like JNK or atypical PKCs, serves as a regulatory mechanism that can impair IRS-1 function. This modification is associated with insulin resistance, as it disrupts insulin signaling by promoting IRS-1 degradation or blocking its interaction with upstream receptors.
Researchers use this antibody to study metabolic disorders such as type 2 diabetes, obesity, and conditions linked to chronic inflammation or oxidative stress, where aberrant Ser323 phosphorylation may contribute to pathological insulin resistance. It is commonly employed in techniques like Western blotting, immunofluorescence, or immunoprecipitation to assess phosphorylation status in cell lines, tissues, or experimental models. The antibody’s specificity for the phosphorylated epitope helps distinguish active regulatory events from total IRS-1 levels, providing insights into dynamic signaling modulation. Understanding Ser323 phosphorylation is also relevant in cancer research, as dysregulated IRS-1 activity may influence tumor growth and metastasis.
