背景信息

Platelet-activating factor receptor (PAFR), a G protein-coupled receptor (GPCR), plays a pivotal role in mediating inflammatory and immune responses. It binds platelet-activating factor (PAF), a potent phospholipid mediator involved in cellular communication during inflammation, allergy, and thrombosis. Structurally, PAFR consists of seven transmembrane domains, characteristic of GPCRs, and activates intracellular signaling pathways such as phospholipase C (PLC), mitogen-activated protein kinase (MAPK), and nuclear factor-κB (NF-κB) upon ligand binding. These pathways regulate processes like leukocyte activation, vascular permeability, and cytokine release.

Recombinant PAFR proteins are engineered to study the receptor’s function, structure, and interactions. Produced via heterologous expression systems (e.g., mammalian HEK293 or insect cells), these proteins retain native receptor activity while enabling scalable purification. Tags like FLAG, His, or GFP are often fused to facilitate detection, localization, or affinity chromatography. Recombinant PAFR is critical for drug discovery, allowing high-throughput screening of antagonists or modulators to treat PAFR-associated diseases, including sepsis, asthma, and cardiovascular disorders. It also aids in structural studies (e.g., cryo-EM or X-ray crystallography) to elucidate ligand-binding mechanisms and conformational changes. Research using recombinant PAFR has advanced understanding of its pathological roles and therapeutic targeting, highlighting its dual potential in pro-inflammatory and homeostatic processes.
