|Product Overview :
||c-Src Kinase (Human) Assay/Inhibitor Screening Assay Kit is a single-site, non-quantitative immunoassay for kinase activity of recombinant catalytic domain of c-Src. Plates are pre-coated with a newly designed "Tyrosine kinase-binding module-1", which can easily bind recombinant catalytic domain of c-Src, subsequently activate c-Src kinase activity on a microtiter plate. The detector antibody is PY-39, an antibody that specifically detects the phosphotyrosine residue on recombinant catalytic domain of c-Src itself, which means that this kit measures the intensity of autophosphorylation of c-Src catalytic domain.
||The Src family of non-receptor protein tyrosine kinases plays critical roles in a variety of cellular signal transduction pathways, regulating such diverse processes as cell division, motility, adhesion, angiogenesis, and survival. Constitutively activated variants of Src family kinases, including the viral oncoproteins v-Src and v-Yes, are capable of inducing malignant transformation of a variety of cell types. Src family kinases, most notably although not exclusively Src, are frequently overexpressed and/or aberrantly activated in a variety of epithelial and non-epithelial cancers. Activation is very common in colorectal and breast cancers, and somewhat less frequent in melanomas, ovarian cancer, gastric cancer, head and neck cancers, pancreatic cancer, lung cancer, brain cancers, and blood cancers. Further, the extent of increased Src family activity often correlates with malignant potential and patient survival. Activation of Src family kinases in human cancers may occur through a variety of mechanisms and is frequently a critical event in tumor progression. Exactly how Src family kinases contribute to individual tumors remains to be defined completely, however they appear to be important for multiple aspects of tumor progression, including proliferation, disruption of cell/cell contacts, migration, invasiveness, resistance to apoptosis, and angiogenesis.
