**Background of PLSCR4 Recombinant Protein**
Phospholipid Scramblase 4 (PLSCR4) is a member of the phospholipid scramblase family, which plays a critical role in maintaining phospholipid asymmetry across cellular membranes. These proteins mediate the bidirectional movement of phospholipids between membrane leaflets, a process essential for cellular functions such as apoptosis, cell activation, and signaling. PLSCR4. encoded by the *PLSCR4* gene, is distinct from other scramblases due to its tissue-specific expression, predominantly observed in the brain, testis, and immune cells.
Recombinant PLSCR4 protein is engineered using biotechnological approaches, often expressed in *E. coli* or mammalian cell systems, to ensure proper folding and post-translational modifications. This purified protein retains the scramblase activity critical for studying lipid redistribution mechanisms in vitro. Structurally, PLSCR4 contains characteristic features of scramblases, including a conserved calcium-binding domain and a hydrophobic region for membrane association.
Research on PLSCR4 has linked it to diverse physiological and pathological processes. It participates in immune responses by facilitating phosphatidylserine (PS) exposure on cell surfaces, a signal for phagocytic clearance of apoptotic cells. Dysregulation of PLSCR4 has been implicated in neurological disorders, cancer progression, and aberrant immune signaling. For instance, studies suggest its role in modulating tumor cell survival and metastasis through lipid-mediated pathways.
The availability of recombinant PLSCR4 enables mechanistic studies, drug screening, and therapeutic development. It serves as a tool to dissect scramblase interactions with membranes, regulatory proteins, or small molecules. Additionally, its potential as a biomarker or therapeutic target in diseases involving membrane dynamics is under exploration.
In summary, PLSCR4 recombinant protein provides a vital resource for understanding lipid metabolism, cellular signaling, and disease mechanisms, bridging molecular biology with translational applications.
