**Background of CAPSL Recombinant Protein**
CAPSL (Calcium-Activated Protein Involved in Secretion and Lysosome Regulation) is a multifunctional protein implicated in cellular processes such as vesicle trafficking, lysosomal function, and secretory pathways. Initially identified through genomic studies, CAPSL is characterized by calcium-binding domains, enabling it to act as a calcium sensor. This property links it to calcium-dependent signaling, a critical regulator of intracellular membrane fusion and cargo release.
Recombinant CAPSL protein is engineered using heterologous expression systems (e.g., *E. coli*, mammalian cells*) to produce purified, functional protein for research and therapeutic applications. Its recombinant form retains calcium-responsive conformational changes, making it valuable for studying lysosomal disorders, autophagy, and exocytosis. CAPSL's role in modulating synaptic vesicle release and lysosomal enzyme activation has also drawn interest in neurodegenerative disease research, particularly Alzheimer's and Parkinson's.
In drug development, CAPSL recombinant protein serves as a tool for high-throughput screening of molecules targeting calcium signaling or lysosomal pathways. Structural studies using recombinant CAPSL have elucidated its interaction partners and mechanism of action. Challenges remain in optimizing expression yield and stability, but advances in protein engineering and purification techniques continue to enhance its utility. Overall, CAPSL recombinant protein bridges basic research and translational applications, offering insights into calcium-mediated cellular regulation and therapeutic potential.
