**Background of CPAMD5 Recombinant Protein**
CPAMD5 (C5a Receptor 1 or C5aR1/CD88) is a G protein-coupled receptor (GPCR) primarily expressed on immune cells, including neutrophils, monocytes, and macrophages. It binds to the complement component C5a, a potent anaphylatoxin generated during complement system activation. The C5a-C5aR1 interaction triggers inflammatory responses, such as chemotaxis, cytokine release, and phagocyte activation, playing a critical role in innate immunity and inflammatory diseases.
CPAMD5 recombinant protein is engineered to mimic the native receptor's extracellular ligand-binding domain. Produced via heterologous expression systems (e.g., mammalian or insect cells), it retains structural and functional integrity for in vitro studies. Researchers use this recombinant protein to investigate C5a-mediated signaling pathways, screen therapeutic inhibitors, or develop diagnostic tools for conditions like sepsis, rheumatoid arthritis, or COVID-19-associated hyperinflammation.
Interest in CPAMD5 has grown due to its dual role in host defense and pathological inflammation. Blocking C5a-C5aR1 signaling with monoclonal antibodies or small molecules has shown therapeutic potential in preclinical models. However, challenges remain in balancing anti-inflammatory efficacy with immune suppression risks. CPAMD5 recombinant protein serves as a vital tool to dissect these mechanisms, aiding drug discovery and advancing precision medicine approaches for inflammatory disorders.
