basic FUNCTION
| acting as a receptor for ATP and ADP coupled to G-proteins that activate both phosphatidylinositol-calcium and adenylyl cyclase second messenger systems |
|
acting as a purinergic nucleotide receptor, G-protein coupled |
|
acting as a rhodopsin-like receptor |
|
endogenous receptor in granulocytes mediating the sustained [Ca2+] increase responsible for their functional activation |
|
implicated in inhibition of neutrophil apoptosis by ATP |
|
highly expressed in CD8+ T cells and natural killer cells and modulates immune cell viability |
