The ABL1 (Abelson murine leukemia viral oncogene homolog 1) protein is a non-receptor tyrosine kinase involved in regulating cell proliferation, differentiation, adhesion, and stress response. It plays critical roles in intracellular signaling pathways, including those mediated by growth factors and cytoskeletal remodeling. Structurally, ABL1 contains SH3 and SH2 domains that modulate protein-protein interactions and a kinase domain responsible for its enzymatic activity. Its activity is tightly regulated by autoinhibitory mechanisms; disruption of these controls can lead to constitutive kinase activation, a hallmark of oncogenic transformation.
The ABL1 gene gained prominence due to its association with chronic myeloid leukemia (CML). Chromosomal translocation t(9;22) generates the BCR-ABL1 fusion gene, encoding a hyperactive tyrosine kinase that drives uncontrolled cell division. This discovery led to the development of tyrosine kinase inhibitors (e.g., imatinib), revolutionizing CML treatment and establishing molecularly targeted cancer therapy.
Recombinant ABL1 proteins are produced using expression systems (e.g., E. coli, mammalian cells) for functional and structural studies. These proteins retain key domains and post-translational modification capabilities, enabling research into kinase mechanisms, drug binding, and resistance mutations (e.g., T315I). Tagged versions (GST, His-tag) facilitate purification and interaction studies. Researchers use recombinant ABL1 to screen inhibitors, map signaling networks, and analyze mutant variants' biochemical properties. Its structural flexibility and role in disease make it a valuable tool for understanding kinase regulation and designing next-generation therapeutics. Recent studies also explore ABL1's involvement in neurodegenerative disorders and bacterial infection responses, expanding its biological significance beyond oncology.
