The AKT1 protein, also known as protein kinase B (PKB), is a serine/threonine kinase central to cellular signaling pathways regulating survival, proliferation, and metabolism. It belongs to the AGC kinase family and is a key mediator of the PI3K/AKT/mTOR pathway, which is frequently dysregulated in cancers, metabolic disorders, and neurodegenerative diseases. AKT1 is activated by phosphorylation at two critical residues (Thr308 and Ser473) upon growth factor stimulation, triggering downstream effects on substrates like GSK-3β, FOXO transcription factors, and TSC2. Its modular structure includes a pleckstrin homology (PH) domain for membrane localization, a catalytic kinase domain, and a regulatory hydrophobic motif.
Recombinant AKT1 protein is produced using engineered expression systems (e.g., E. coli, insect, or mammalian cells) to enable functional and structural studies. Purification often involves affinity tags (e.g., His-tag, GST) for streamlined isolation. This recombinant tool is vital for investigating AKT1's enzymatic activity, substrate interactions, and regulatory mechanisms in vitro. Researchers use it to screen inhibitors targeting cancer-associated AKT1 hyperactivation or to study mutations linked to developmental syndromes (e.g., Proteus syndrome) and drug resistance. Its role in insulin signaling and apoptosis further makes it relevant for metabolic disease and neurodegeneration research. By providing a controlled source of active kinase, recombinant AKT1 accelerates both basic research and therapeutic development, particularly in precision oncology.
