Nck (NCK1, NCK adaptor protein 1, Cytoplasmic protein NCK1, MGC12668, Nck-1, NCKalpha, SH2/SH3 adaptor protein NCK-alpha)

Nck is a highly conserved, oncogenic protein, encoding one SH2 and three SH3 domains, the Src homology motifs found in nonreceptor tyrosine kinases, Ras GTPase-activating protein, phosphatidylinositol 3-kinase, and phospholipase C-g. Nck is an oncogenic protein and a common target for the action of different surface receptors. Nck is widely expressed in various tissues and in cell lines from human, murine and rat origins. Nck is phosphorylated on tyrosine, serine, and threonine residues in response to stimulation of EGF and PDGF in A431 and NIH 3T3 cells, respectively. Like other SH2-containing proteins, Nck is associated with tyrosine- autophosphorylated EGF or PDGF receptors via its SH2 domain. Overexpression of Nck leads to transformation of NIH 3T3 cells. Nck binds through its second SH3 domain to WIP, and Nck binds to WIP at a site (aa321-415). \n\nApplications: \nSuitable for use in Western Blot and Immunoprecipitation. Other applications not tested.\n\nRecommended Dilutions:\nWestern Blot: 0.1-1ug/ml detected Nck in human A431 carcinoma cells. Previous lots detected Nck in mouse 3T3/A31 fibroblasts and rat L6 skeletal fibroblasts. Non-stimulated A431 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with N0550-05 (0.1ug/ml). Proteins were visualized using IgG (HRP) goat anti-rabbit and a chemilluminescence detection system.\nImmunoprecipitation: 5ug immunprecipitates Nck from a lysate of human A431 carcinoma cells, mouse 3T3/A31 fibroblasts and rat L6 skeletal fibroblasts.\nOptimal dilutions to be determined by the researcher.\n\nPositive Antigen Control (Included): \nA0001-50: A431 Cells, Non-Stimulated in RIPA Buffer, Sample Buffer.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
