Background: P2Y purinoceptor 11 encodes P2Y11 (P2Y11) which is a receptor for ATP and ADP coupled to G-proteins that activate both phosphatidylinositol-calcium and adenylyl cyclase second messenger systems. P2Y11 receptor is unique amongst P2Y receptors with its coupling to the adenylyl cyclase pathway. Through this mechanism, released nucleotides can increase in P2Y11-containing cells. P2Y11 receptor has been reported to be involved in the granulocytic differentiation of promyelocytes and in the maturation of monocyte-derived dendritic cells.
