ATP5PB, also known as ATP synthase F1 subunit beta, is a critical component of the mitochondrial ATP synthase complex, which plays a central role in cellular energy production. This nuclear-encoded gene produces the beta subunit of the F1 portion of ATP synthase, an enzyme located in the inner mitochondrial membrane. As part of the F-type ATPase family, ATP5PB contributes to the catalytic core responsible for synthesizing ATP from ADP and inorganic phosphate during oxidative phosphorylation, utilizing the proton gradient generated by the electron transport chain.
Recombinant ATP5PB protein is engineered to study the structure, function, and regulatory mechanisms of ATP synthase. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cell lines), the recombinant protein is often purified with affinity tags (e.g., His-tag) to facilitate isolation. Its production enables detailed biochemical analyses, including enzymatic activity assays, protein-protein interaction studies, and investigations into mitochondrial disorders linked to ATP synthase dysfunction.
Research involving recombinant ATP5PB has broad implications. Mutations in ATP5PB are associated with mitochondrial diseases, neurodegenerative conditions, and metabolic disorders. The protein also serves as a tool for exploring cancer metabolism, as cancer cells often exhibit altered ATP synthase activity. Additionally, recombinant ATP5PB is used to generate antibodies for diagnostic applications and to screen potential therapeutic compounds targeting energy metabolism pathways. Its study advances understanding of cellular bioenergetics and supports drug development for diseases tied to mitochondrial dysfunction.
