背景信息

**Background of LTP2 Recombinant Protein**

Lipid Transfer Protein 2 (LTP2) belongs to a family of small, cysteine-rich proteins widely distributed in plants. These proteins are characterized by their ability to bind and transfer hydrophobic molecules, such as lipids or cuticular components, across aqueous environments. LTP2 is primarily associated with plant defense mechanisms, playing roles in pathogen resistance, cuticle formation, and cellular signaling. Unlike its more studied counterpart LTP1. which is often linked to allergenic properties, LTP2 exhibits distinct structural features and tissue-specific expression patterns, particularly in seeds and epidermal tissues.

The recombinant form of LTP2 is produced using genetic engineering techniques, where the LTP2 gene is cloned into expression vectors (e.g., *E. coli* or yeast systems) to enable large-scale protein synthesis. Recombinant LTP2 retains the native protein's functional properties, including its lipid-binding capacity and stability under physiological conditions. This makes it a valuable tool for studying plant-pathogen interactions, lipid trafficking, and membrane dynamics in vitro. Additionally, its antimicrobial and emulsifying properties have sparked interest in biotechnological applications, such as food preservation, drug delivery systems, and agricultural bioengineering.

Research on LTP2 also contributes to understanding plant adaptation to environmental stress, as its expression is modulated by abiotic factors like drought or salinity. By elucidating LTP2's molecular interactions, scientists aim to engineer crops with enhanced resilience or develop novel biomaterials. Despite its potential, challenges remain in optimizing recombinant production yields and minimizing post-translational modifications in heterologous systems. Ongoing studies continue to explore LTP2's multifunctional roles, bridging fundamental plant biology and applied biotechnology.
