**注意**:目前公开文献中针对**重组人OR4P4蛋白**的直接研究较少,上述文献侧重OR4P4的疾病相关性。其重组表达可能面临挑战(如膜蛋白难溶性),建议参考其他嗅觉受体重组技术(如使用杆状病毒/哺乳动物表达系统)。如需具体重组方法,可尝试检索“olfactory receptor OR family recombinant expression”等关键词。
OR4P4. a member of the olfactory receptor (OR) family 4. is a G protein-coupled receptor (GPCR) encoded by the OR4P4 gene in humans. Olfactory receptors are primarily responsible for detecting odorant molecules in the nasal epithelium, but emerging research highlights their ectopic expression in non-olfactory tissues, suggesting broader physiological roles. OR4P4. specifically, has been detected in tissues such as the prostate, testis, and brain, though its exact ligands and signaling pathways remain poorly characterized.
Structurally, OR4P4 features seven transmembrane domains typical of GPCRs, facilitating signal transduction through G protein-mediated cascades. Its function outside the olfactory system is under investigation; studies propose potential involvement in cellular processes like proliferation, apoptosis, or chemotaxis. For instance, OR4P4 may interact with endogenous metabolites or environmental cues in peripheral tissues, influencing disease pathways such as cancer progression or neurological disorders.
Recombinant OR4P4 protein is produced using heterologous expression systems (e.g., HEK293 cells) to study its biochemical properties, ligand-binding specificity, and interactions. This tool aids in deciphering its role in health and disease, offering therapeutic targeting opportunities. Despite limited data, OR4P4 exemplifies the expanding paradigm of ORs as multifaceted sensors beyond olfaction, driving interest in their systemic functions and clinical relevance.
