Key Sites for P2X Receptor Function and Multimerization: Overview of Mutagenesis Studies on a Structural Basis

P2X receptors constitute a seven-member family (P2X1-7) of extracellular ATP-gated cation channels of widespread expression. Because P2X receptors have been implicated in neurological, inflammatory and cardiovascular diseases, they constitute promising drug targets. Since the first P2X cDNA sequences became available in 1994, numerous site-directed… CONTINUE READING
