The Phospho-ABL1(Y393)/ABL2(Y439) antibody is designed to detect the activated forms of ABL1 (Abelson tyrosine-protein kinase 1) and ABL2 (Abelson-related gene, Arg), non-receptor tyrosine kinases involved in cell proliferation, differentiation, adhesion, and stress response. ABL1 and ABL2 share high structural homology, containing SH3. SH2. and kinase domains, but differ in their N-terminal regions. Activation of these kinases requires phosphorylation at specific tyrosine residues: Y393 in ABL1 and Y439 in ABL2 (analogous sites due to sequence alignment). These autophosphorylation events stabilize the active kinase conformation, enabling downstream signaling through pathways like RAS-MAPK, PI3K/AKT, and STAT.
Dysregulation of ABL kinases, particularly through chromosomal translocations (e.g., BCR-ABL1 in chronic myeloid leukemia), drives oncogenic signaling. The Phospho-ABL1(Y393)/ABL2(Y439) antibody is thus critical for studying ABL activation status in cancers and evaluating therapeutic responses to tyrosine kinase inhibitors (TKIs) like imatinib. It is widely used in techniques such as Western blotting, immunohistochemistry, or flow cytometry to assess phosphorylation-dependent ABL activity in cell lines, primary tissues, or preclinical models.
This antibody’s specificity for the phosphorylated forms ensures accurate detection of active ABL kinases, distinguishing them from inactive states. Researchers rely on it to investigate ABL’s role in disease mechanisms, drug resistance, and to validate targeted therapies. Proper controls (e.g., kinase-inactive mutants or TKI-treated samples) are essential to confirm signal specificity.
