**Background of BCL2L2 Recombinant Protein**
BCL2L2. commonly known as BCL-W, is a member of the BCL-2 protein family, which plays a pivotal role in regulating mitochondrial-dependent apoptosis. Encoded by the *BCL2L2* gene, this anti-apoptotic protein shares structural homology with other BCL-2 family members, including conserved BCL-2 homology (BH) domains (BH1-BH4). BCL-W primarily inhibits apoptosis by binding pro-apoptotic proteins like BAX and BAK, thereby preventing mitochondrial outer membrane permeabilization (MOMP) and blocking cytochrome *c* release, a key step in the intrinsic apoptosis pathway.
Recombinant BCL2L2 protein is engineered using expression systems such as *E. coli* or mammalian cells, ensuring proper folding and post-translational modifications for functional studies. Purification techniques like affinity chromatography yield high-purity protein, often tagged for detection (e.g., His or GST tags). This recombinant tool is widely used to study protein-protein interactions, screen small-molecule inhibitors, and elucidate structural mechanisms of apoptosis regulation.
BCL-W is implicated in cancer progression, where its overexpression in tumors (e.g., colorectal, glioblastoma) confers resistance to chemotherapy. Consequently, recombinant BCL2L2 aids in developing BH3 mimetics—drugs that disrupt anti-apoptotic interactions to restore cell death in malignancies. Beyond oncology, it contributes to research on neurodegenerative diseases and tissue homeostasis. However, its tissue-specific ___expression (e.g., in testes and neurons) suggests nuanced roles beyond general apoptosis inhibition, warranting further exploration.
Overall, BCL2L2 recombinant protein serves as a critical reagent for dissecting apoptotic pathways and advancing targeted therapies, highlighting its dual significance in basic research and translational medicine.
