| Introduction | Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor for pleiotrophin (PTN), a growth factor involved in embryonic brain development. In ALK-expressing cells, PTN induces phosphorylation of both ALK and the downstream effectors IRS-1, Shc, PLCγ, and PI3 kinase. ALK was originally discovered as a nucleophosmin (NPM)-ALK fusion protein produced by a translocation. Investigators have found that the NPM-ALK fusion protein is a constitutively active, oncogenic tyrosine kinase associated with anaplastic lymphoma. 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.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. |

| Usage | |
|---|---|
| Application | WB |
| Dilutions | Western Blot (1:1000) |
| MW(KDa) | 220 (ALK), 80 (NPM-ALK) |
| Reactivity | Human |
| Sensitivity | Endogenous |
| Specificity | This antibody detects ALK only when phosphorylated at Tyr1278, which is equivalent to Tyr338 of NPM-ALK. This antibody also reacts with leukocyte tyrosine kinase (LTK) phosphorylated at Tyr672, and may cross-react with other activated protein tyrosine kinases including Bcr-Abl. |
