Activity summary

The DP1 receptor also known as the prostaglandin D2 receptor 1 is a G-protein-coupled receptor with a molecular mass of approximately 44 kDa. This receptor binds to prostaglandin D2 (PGD2) and is found in various tissues including the central nervous system lungs and some immune cells. The presence of DP1 in these tissues suggests a role in multiple physiological processes reflecting its distribution in the body.

Biological function summary

Prostaglandin D2 (PGD2) plays a significant role in mediating inflammatory and allergic responses. The DP1 receptor is part of a signaling complex that modulates smooth muscle relaxation inhibition of platelet aggregation and sleep induction. Its expression in both neural and peripheral tissues underlines its involvement in a range of biological functions including the regulation of sleep-wake cycles and inflammation.

Pathways

The DP1 receptor contributes significantly to the prostaglandin signaling pathway which involves other prostaglandin receptors such as DP2 and EP receptors. This pathway mediates various physiological responses including vasodilation and immune modulation. The signaling interactions between DP1 and these related receptors help coordinate complex biological processes such as the regulation of vascular tone and inflammatory responses.

Associated diseases and disorders

Abnormal DP1 signaling relates to asthma and allergic rhinitis conditions where inflammation and immune response are dysregulated. Overactivation or altered regulation of DP1 can exacerbate these diseases often involving other proteins like COX-2 which elevate levels of PGD2 during inflammation. Understanding DP1's role offers potential therapeutic angles for managing allergic and inflammatory diseases.
