The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.1 - 1 µg/ml. Detects a band of approximately 165 kDa (predicted molecular weight: 132 kDa).
Use a concentration of 2 - 5 µg/ml.
Use a concentration of 0.01 - 0.1 µg/ml.
Use at an assay dependent concentration.
機能May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit.
関連疾患Polymorphisms in IRS1 may be involved in the etiology of non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853].
翻訳後修飾Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Ser-312 phosphorylation inhibits insulin action through disruption of IRS1 interaction with the insulin receptor. Phosphorylation of Tyr-896 is required for GRB2-binding.
1µg peptides were blotted onto a nitrocellulose membrane followed by ab66154 at 1/1000 dilution.
B: IRS1(non phosphorylated)
C: Non-related Phosphopeptide
