Activity summary

CCR3 also known as C-C chemokine receptor type 3 is a protein that acts as a receptor for chemokines. The molecular weight of CCR3 is approximately 43 kDa. This protein is predominantly expressed in eosinophils and basophils and is also found in specific subsets of T cells. The expression of CCR3 in these cells plays an important role in directing their migration and activity. This receptor is part of the G protein-coupled receptor family which transduce signals across the cell membrane.

Biological function summary

CCR3 facilitates chemokine-directed migration of white blood cells an essential function for immune responses. It binds to several chemokines like eotaxin eotaxin-2 and RANTES which mediates the recruitment of eosinophils and other cells to sites of inflammation. CCR3 does not form part of a protein complex instead it interacts directly with its chemokine ligands. This activity enhances the body's ability to respond to allergic reactions and inflammatory processes.

Pathways

CCR3 plays a role in the signaling pathways that orchestrate immune cell trafficking and activation. It is involved in the chemokine signaling pathway which regulates cell movement and positioning and the calcium mobilization pathway through its ligand interaction. CCR3 along with other receptors like CCR5 and CXCR4 facilitates the communication between immune cells aiding in directed cell movement towards the inflammation site.

Associated diseases and disorders

CCR3 is notably involved in allergic disorders and asthma. Its expression influences the recruitment of eosinophils which are key players in these conditions. This receptor is linked to heightened inflammatory responses leading to tissue damage in chronic allergic diseases. The interaction of CCR3 with chemokines like eotaxin is significant in the pathophysiology of these diseases making it a potential target for therapeutic intervention to mitigate symptoms of chronic allergic responses.
