Target type: molecularfunction
Combining with prostaglandin D (PGD(2)) to initiate a change in cell activity. [ISBN:0198506732]
Prostaglandin D receptor activity is a molecular function that involves the binding and recognition of prostaglandin D2 (PGD2), a lipid mediator with diverse biological roles. PGD2 exerts its effects through two distinct G protein-coupled receptors: DP1 and DP2.
DP1 receptors, also known as CRTH2, are primarily expressed on Th2 cells, eosinophils, and mast cells. Activation of DP1 receptors leads to the downstream signaling cascade involving the G protein Gs, resulting in the production of cAMP. This cAMP signaling pathway triggers a variety of cellular responses, including chemotaxis, degranulation, and cytokine release, contributing to the pathogenesis of allergic inflammation and asthma.
DP2 receptors, also known as the prostaglandin D2 receptor, are expressed on various cells, including neurons, smooth muscle cells, and immune cells. Activation of DP2 receptors primarily involves the G protein Gi, leading to the inhibition of adenylyl cyclase and a decrease in cAMP levels. This signaling pathway is implicated in regulating sleep, inflammation, and pain.
In summary, prostaglandin D receptor activity plays a crucial role in mediating the physiological and pathophysiological effects of PGD2. Its interaction with distinct G protein-coupled receptors, DP1 and DP2, triggers diverse signaling pathways that regulate a wide range of cellular functions, including inflammation, chemotaxis, degranulation, cytokine release, sleep, and pain.'
