背景信息

**Background of PHB2 Recombinant Protein**

Prohibitin-2 (PHB2), a member of the prohibitins family, is a highly conserved protein ubiquitously expressed in eukaryotic cells. Initially identified as an antiproliferative protein, PHB2 shares structural homology with PHB1. forming a heterodimeric complex in the mitochondrial inner membrane. This complex plays a critical role in maintaining mitochondrial integrity, including cristae morphogenesis, oxidative phosphorylation, and reactive oxygen species (ROS) regulation. Beyond its mitochondrial role, PHB2 localizes to the nucleus, where it participates in transcriptional regulation, chromatin remodeling, and cell cycle control.

Recombinant PHB2 protein is engineered through molecular cloning techniques, often expressed in bacterial or mammalian systems, followed by purification to ensure high specificity and activity. Its production enables researchers to study PHB2's molecular interactions, post-translational modifications, and functional mechanisms in vitro. Studies using recombinant PHB2 have elucidated its involvement in cellular stress responses, apoptosis, and aging. For instance, PHB2 interacts with proteins like PARL and Drp1. modulating mitochondrial dynamics and mitophagy.

Emerging evidence links PHB2 dysregulation to pathologies, including cancer, neurodegeneration, and metabolic disorders. In cancer, PHB2 exhibits dual roles, acting as a tumor suppressor or promoter depending on cellular context. Its nuclear functions also implicate PHB2 in epigenetic regulation, influencing gene expression patterns associated with disease progression. Recombinant PHB2 serves as a valuable tool for drug screening, structural studies, and therapeutic development targeting mitochondrial or nuclear pathways.

Overall, PHB2's multifunctional nature underscores its biological significance, with recombinant protein technology accelerating mechanistic insights and translational applications.
