**作者**：Hui Zhuang, Hiroaki Matsunami
**摘要**：文章系统比较了RTP1、RTP2及REEP1在体外重组系统中的协同作用。实验表明，重组RTP1不仅促进ORs膜表达，还能稳定受体-G蛋白偶联效率，为构建高效异源OR筛选平台提供理论依据。(*PNAS, 2008*)
3. **文献名称**：*A humanized system for functional expression of odorant receptors*
**作者**：Elena Shirokova 等
**摘要**：通过共表达RTP1、Ric8b等辅助蛋白，优化了哺乳动物细胞中重组人ORs的功能性表达体系。研究显示RTP1对维持受体构象完整性具有特异性，其缺失导致配体结合能力下降>60%。(*JBC, 2005*)

**注**：RTP1常作为嗅觉受体研究中的核心辅助蛋白，相关文献多聚焦于其促进GPCR膜定位及信号转导机制。如需技术类文献(如重组蛋白纯化方法)，建议补充更具体的实验方向。
Recombinant human RTP1 (Receptor Transporting Protein 1) is a chaperone protein crucial for the functional expression of olfactory receptors (ORs) in heterologous systems. Olfactory receptors, which detect odorant molecules, are notoriously difficult to express in standard cell lines due to their complex membrane localization requirements. RTP1. alongside its homolog RTP2. forms part of a protein complex that facilitates the trafficking of nascent ORs from the endoplasmic reticulum to the cell surface. This process enhances receptor stability and ligand-binding capacity.
Originally identified in olfactory epithelium studies, RTP1 is a small, soluble protein containing conserved coiled-coil domains that mediate interactions with ORs and other trafficking partners like REEP1. Its recombinant form is widely used in biomedical research to reconstitute functional odorant receptors *in vitro*, enabling high-throughput screening for odorant ligands or drug discovery targeting OR-related pathways.
Beyond olfaction, RTP1 has implications in studying ectopic ORs found in non-olfactory tissues, such as the brain, kidneys, or cancers, where they may regulate physiological processes or disease progression. The development of recombinant RTP1 has significantly advanced structural studies, receptor deorphanization efforts, and therapeutic explorations involving orphan G protein-coupled receptors (GPCRs). Its application in synthetic biology also supports engineered cellular biosensors for environmental or diagnostic purposes.
