描述 | The Met Signaling Antibody Sampler Kit provides an economical means to investigate Met signaling. The kit contains primary and secondary antibodies to perform four Western blots with each antibody. |
目标/特异性 | Each antibody in the Met Signaling Antibody Sampler Kit recognizes endogenous levels of its specific target and does not cross-react with other family members unless otherwise indicated. Phospho-Met (Tyr1234/1235) (D26) Rabbit mAb may cross-react with overexpressed tyrosine phosphorylated Src proteins in Western blot. Phospho-Met (Tyr1349) (130H2) Rabbit mAb may cross-react with other activated protein tyrosine kinases. Phospho-Met (Tyr1003) (13D11) Rabbit mAb may cross-react with other activated protein tyrosine kinases. Phospho-Gab1 (Tyr307) Antibody cross-reacts with phosphorylated Gab2 and potentially with phosphorylated Gab3. |

背景 | Met, a high affinity tyrosine kinase receptor for hepatocyte growth factor (HGF, also known as scatter factor), is a disulfide-linked heterodimer made of 45 kDa α- and 145 kDa β-subunits (1,2). The α-subunit and the amino-terminal region of the β-subunit form the extracellular domain. The remainder of the β-chain spans the plasma membrane and contains a cytoplasmic region with tyrosine kinase activity. Interaction of Met with HGF results in autophosphorylation at multiple tyrosines, which recruit several downstream signaling components, including Gab1, c-Cbl and PI3 kinase (3). These fundamental events are important for all of the biological functions involving Met kinase activity. Addition of a phosphate at cytoplasmic Tyr1003 is essential for ubiquitination and Met protein degradation (4). Phosphorylation of Tyr1234/1235 in the Met kinase domain is critical to kinase activation. Phosphorylation of Tyr1349 in the Met cytoplasmic domain provides a direct binding site for Gab1 (5). Altered Met levels and/or tyrosine kinase activities are found in several types of tumors, including renal, colon and breast cancers. Thus, Met is an attractive cancer therapeutic and diagnostic target (6). |
