**Background of STARD7 Recombinant Protein**
STARD7 (STAR-related lipid transfer domain protein 7) belongs to the STARD protein family, which is characterized by a conserved START (STAR-related lipid transfer) domain responsible for binding and transporting lipids. This family plays critical roles in lipid metabolism, signaling, and membrane homeostasis. STARD7. in particular, is a multifunctional protein implicated in intracellular lipid trafficking, notably for phosphatidylcholine (PC), a major phospholipid essential for membrane structure and function.
Structurally, STARD7 contains an N-terminal mitochondrial targeting sequence and a C-terminal START domain. It localizes to both mitochondria and the cytoplasm, suggesting dual roles in cellular lipid distribution. In mitochondria, STARD7 maintains membrane integrity by facilitating PC transfer, crucial for mitochondrial respiration and apoptosis regulation. Cytoplasmic STARD7 may influence lipid signaling pathways, potentially interacting with kinases or other mediators of cell proliferation and stress responses.
STARD7's involvement in metabolic regulation links it to diseases such as cancer, diabetes, and non-alcoholic fatty liver disease (NAFLD). For example, reduced STARD7 expression correlates with mitochondrial dysfunction in hepatic steatosis, while its overexpression in certain cancers may promote tumor survival via lipid metabolism reprogramming.
Recombinant STARD7 protein is produced using expression systems like *E. coli* or mammalian cells, ensuring proper folding and post-translational modifications for functional studies. It serves as a tool to investigate lipid-protein interactions, enzymatic activity, and mechanisms underlying metabolic disorders. Purification typically involves affinity tags (e.g., His-tag) followed by chromatography, yielding high-purity protein for *in vitro* assays, structural studies, or therapeutic exploration.
Research on STARD7 continues to uncover its biological significance, highlighting its potential as a therapeutic target or biomarker for lipid-related diseases. Its recombinant form remains pivotal for dissecting molecular pathways and developing targeted interventions.
