**Recombinant human CLPB protein** is a genetically engineered version of the **caseinolytic peptidase B (CLPB) protein**, a member of the AAA+ ATPase superfamily. Native CLPB plays a critical role in mitochondrial proteostasis, functioning as a **ATP-dependent chaperone** that disaggregates misfolded proteins and facilitates protein quality control. It is implicated in stress responses, particularly under heat shock or oxidative stress, by collaborating with the mitochondrial protease complex.
CLPB mutations are linked to human diseases, including **severe mitochondrial disorders** (e.g., 3-methylglutaconic aciduria type VII) characterized by neurodevelopmental impairments and metabolic dysregulation. Recombinant CLPB is produced in heterologous systems (e.g., *E. coli* or mammalian cells*) to study its biochemical activities, structural dynamics, and disease mechanisms. Researchers leverage the recombinant protein to explore its **ATPase activity**, substrate interactions, and role in resolving protein aggregates, which has therapeutic implications for neurodegenerative diseases and aging.
Its recombinant form also aids in drug screening for mitochondrial dysfunctions and serves as a tool to decipher CLPB’s regulatory network within mitochondrial stress pathways. Studies continue to uncover its dual roles in **proteolysis inhibition** and **aggregase activity**, highlighting its complexity in cellular proteostasis.
