Peptide Name: NDR1 (278-285) pS281+pT282
Product Use: Services as a blocking peptide for use with the NDR1-pS281+pT282 rabbit polyclonal antibody (Cat. No.: AB-PK731) that is also available from Kinexus. This phosphopeptide may also be useful as a substrate for screening the phosphatase activity of protein phosphatases. The peptide sequence is located in the protein kinase catalytic domain activation T loop region between subdomains VII and VIII. S281 phosphorylation stimulates phosphotransferase activity. T282 phosphorylation is predicted to be stimulatory for phosphotransferase activity.
Peptide Production Method: Solid-phase peptide synthesis
Peptide Origin: Homo sapiens
Peptide Sequence: LAF-pS-pT-VGT
Peptide Modifications N Terminus: Free amino

Scientific Background: NDR1 (STK38) is a protein-serine/threonine kinase of the AGC group and NDR family. It is activated by binding of S100B, which releases autoinhibitory N-lobe interactions, enabling ATP to bind and the autophosphorylation of S281. Phosphorylation at S281 increases phosphotransferase activity and interaction with MOBP. T444 then undergoes calcium-dependent phosphorylation by an upstream kinase. Interactions between phosphorylated T444 and the N-lobe promote additional structural changes that complete the activation of the kinase. Phosphorylation at T74 induces interaction with S100B. T444 then undergoes calcium-dependent phosphorylation by an upstream kinase. T74A, K118A, S281A, and T444A mutations are involved in decreased or loss of autophosphorylation and kinase activity. NDR1 is a negative regulator of MAP3K1/2 signalling. It converts MAP3K2 from its phosphorylated form to its nonphosphorylated form and inhibits autophosphorylation of MAP3K2. NDR1 is an important regulator of Myc's oncogenic activity in human B-cell lymphomas. It also regulates G/S cell cycle transition. The MAPK/ERK pathway has been implicated in oncogenesis as either a promoter or inhibitor depending on the cancer system.
