ALK (Anaplastic Lymphoma Kinase) is a receptor tyrosine kinase implicated in cellular proliferation, survival, and differentiation. Its dysregulation, often via gene fusions (e.g., EML4-ALK) or activating mutations, drives oncogenesis in cancers like non-small cell lung cancer (NSCLC), neuroblastoma, and anaplastic large-cell lymphoma. Phosphorylation at tyrosine 1604 (Tyr1604) is a critical post-translational modification linked to ALK activation. This site resides within the kinase domain and is autophosphorylated upon ligand binding or constitutive activation in fusion proteins, stabilizing ALK's active conformation and enabling downstream signaling through pathways like MAPK, PI3K/AKT, and JAK/STAT.
Antibodies targeting ALK phosphorylated at Tyr1604 (p-ALK Tyr1604) are essential tools for studying ALK activation status in research and diagnostics. They enable detection of activated ALK in cell lysates (via Western blot) or tissue samples (via immunohistochemistry), aiding in cancer subtype classification, drug response monitoring, and mechanistic studies of ALK inhibitors (e.g., crizotinib, alectinib). Specificity validation is crucial, as off-target binding to related phosphorylated kinases may occur. Proper sample handling (e.g., rapid fixation to preserve phosphorylation) ensures reliable results. These antibodies have advanced understanding of ALK-driven malignancies and remain pivotal in developing targeted therapies.
