背景信息

**Background of FIS1 Recombinant Protein**

FIS1 (Fission Mitochondrial 1) is a conserved eukaryotic protein critical for regulating mitochondrial and peroxisomal fission, processes essential for maintaining cellular organelle dynamics. Initially identified in yeast, FIS1 homologs have been characterized in mammals, plants, and other organisms. Structurally, FIS1 contains a C-terminal transmembrane domain anchoring it to the outer mitochondrial or peroxisomal membrane and an N-terminal tetratricopeptide repeat (TPR) domain that facilitates interactions with downstream fission machinery components, such as dynamin-related proteins (e.g., DRP1).

Recombinant FIS1 protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cell cultures) to enable in vitro studies of its structure, function, and interactions. The recombinant form is typically purified via affinity tags (e.g., His-tag) and validated for activity in binding assays or fission reconstitution experiments. Its production has advanced research into mitochondrial dynamics, particularly in understanding how dysregulated fission contributes to pathologies like neurodegenerative diseases (e.g., Alzheimer’s, Parkinson’s), metabolic disorders, and cancer.

Studies using FIS1 recombinant protein have elucidated its role in apoptosis, mitophagy, and cellular stress responses. For instance, excessive mitochondrial fission mediated by FIS1/DRP1 is linked to fragmented mitochondrial networks in cancer cells, influencing metastasis and chemoresistance. Conversely, impaired FIS1 function correlates with aggregated mitochondria and neuronal degeneration.

Beyond basic research, recombinant FIS1 serves as a tool for drug screening targeting mitochondrial dysfunction. Inhibitors or enhancers of FIS1-mediated fission hold therapeutic potential, driving interest in structural and functional characterization. Despite progress, questions remain about post-translational modifications, tissue-specific regulation, and interplay with fusion proteins (e.g., MFN1/2). Continued use of recombinant FIS1 is vital for unraveling these complexities in organelle biology and disease mechanisms.
