Abstract
Nucleotides are ubiquitous intercellular messengers whose actions are media ted by specific receptors. Since the first clonings in 1993, it is known th at nucleotide receptors belong to two families: the ionotropic P2X receptor s and the metabotropic P2Y receptors. Five human P2Y receptor subtypes have been cloned so far and a sixth one must still be isolated. In this review we will show that they differ by their preference for adenine ver-sits urac il nucleotides and triphospho versus diphospho nucleotides, as well as by t heir transduction mechanisms and cell expression.
