**Background of Recombinant Human MIPEP Protein**
Mitochondrial Intermediate Peptidase (MIPEP), encoded by the *MIPEP* gene, is a metalloprotease predominantly located in the mitochondrial matrix. It plays a critical role in processing precursor proteins imported into mitochondria. Specifically, MIPEP cleaves an octapeptide sequence from the N-terminus of intermediate-sized precursors, facilitating their maturation into functional proteins involved in mitochondrial metabolism, energy production, and cellular homeostasis. This step is essential for maintaining mitochondrial integrity and regulating processes such as oxidative phosphorylation, amino acid metabolism, and apoptosis.
Recombinant human MIPEP protein is generated through genetic engineering, typically expressed in *E. coli* or mammalian cell systems, allowing large-scale production for research and therapeutic exploration. Its recombinant form retains enzymatic activity, enabling studies on substrate specificity, structural analysis, and interactions with mitochondrial import machinery. Dysregulation or mutations in MIPEP are linked to mitochondrial disorders, cardiomyopathy, and neurological impairments, highlighting its clinical relevance. Research on recombinant MIPEP aims to elucidate disease mechanisms, screen potential drug candidates, and develop gene therapies targeting mitochondrial dysfunction. Additionally, it serves as a tool for investigating protein import defects and mitochondrial proteostasis in aging and degenerative diseases.
