| Size | 100 µl |
| Reactivity | H |
| Sensitivity | Endogenous |
| Molecular Weight (kDa) | 80 (NPM-ALK) 220 (ALK) |
| Source/Isotype | Rabbit |
| Application/Dilution | {Western Blotting: 1:1000, Immunoprecipitation: 1:50} |
| Storage | Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody. |
| Specificity/Sensitivity | Phospho-ALK (Tyr1078) Antibody detects ALK only when phosphorylated at Tyr1078, which is equivalent to Tyr138 in NPM-ALK. This antibody may also cross-react with other overexpressed tyrosine phosphorylated proteins. |
| Species Reactivity | Human |
| Source/Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr1078 of human ALK protein. Antibodies are purified by protein A and peptide affinity chromatography. |
| Background | Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor for pleiotrophin (PTN), a growth factor involved in embryonic brain development (1-3). In ALK-expressing cells, PTN induces phosphorylation of both ALK and the downstream effectors IRS-1, Shc, PLCγ, and PI3 kinase (1). ALK was originally discovered as a nucleophosmin (NPM)-ALK fusion protein produced by a translocation (4). Investigators have found that the NPM-ALK fusion protein is a constitutively active, oncogenic tyrosine kinase associated with anaplastic lymphoma (4). Research literature suggests that activation of PLCγ by NPM-ALK may be a crucial step for its mitogenic activity and involved in the pathogenesis of anaplastic lymphomas (5).A distinct ALK oncogenic fusion protein involving ALK and echinoderm microtubule-associated protein like 4 (EML4) has been described in the research literature from a non-small cell lung cancer (NSCLC) cell line, with corresponding fusion transcripts present in some cases of lung adenocarcinoma. The short, amino-terminal region of the microtubule-associated protein EML4 is fused to the kinase domain of ALK (6-8).Phosphorylation of ALK on Tyr1078 was identified at Cell Signaling Technology (CST) using PhosphoScan®, CSTs LC-MS/MS platform for phosphorylation site discovery. Phosphorylation of ALK at Tyr1078 was observed in select carcinoma cell lines and in tumors. |
