Molecular physiology of P2X receptors

RA North - Physiological reviews, 2002 - journals.physiology.org
P2X receptors are membrane ion channels that open in response to the binding of
extracellular ATP. Seven genes in vertebrates encode P2X receptor subunits, which are 40 …

Co-expression of P2X1 and P2X5 receptor subunits reveals a novel ATP-gated ion channel

GE Torres, WR Haines, TM Egan, MM Voigt - Molecular pharmacology, 1998 - ASPET
P2X receptors are a family of ion channels gated by extracellular ATP. Each member of the
family can form functional homomeric channels, but only P2X2 and P2X3 have been shown …

ATP binding at human P2X1 receptors: contribution of aromatic and basic amino acids revealed using mutagenesis and partial agonists

JA Roberts, RJ Evans - Journal of Biological Chemistry, 2004 - ASBMB
P2X receptors comprise a family of ATP-gated ion channels with the basic amino acids Lys-
68, Arg-292, and Lys-309 (P2X 1 receptor numbering) contributing to agonist potency. In …

Mutational analysis of the conserved cysteines of the rat P2X2 purinoceptor

JD Clyne, LF Wang, RI Hume - Journal of Neuroscience, 2002 - Soc Neuroscience
P2X receptors are ATP-gated cation channels that are widely expressed in the brain. The
extracellular domains of all seven P2X receptors contain 10 conserved cysteines, which …

[HTML][HTML] Desensitization of the P2X2 receptor controlled by alternative splicing

U Brändle, P Spielmanns, R Osteroth, J Sim… - FEBS letters, 1997 - Elsevier
P2X receptors are ion channels gated by extracellular ATP. We report here cloning of a
P2X2 receptor splice variant (P2X2-2) carrying a 207 bp deletion in the intracellular C …

Biochemical and functional evidence for heteromeric assembly of P2X1 and P2X4 subunits

A Nicke, D Kerschensteiner, F Soto - Journal of neurochemistry, 2005 - Wiley Online Library
P2X receptors are ligand‐gated ion channels activated by extracellular ATP. In expression
systems, P2X subunits form homo‐and heterotrimeric receptors. Heteromerization is also …

[HTML][HTML] P2X1 and P2X3 receptors form stable trimers: a novel structural motif of ligand‐gated ion channels

A Nicke, HG Bäumert, J Rettinger, A Eichele… - The EMBO …, 1998 - embopress.org
P2X receptors are cation channels gated by extracellular ATP. The seven known P2X
isoforms possess no sequence homology with other proteins. Here we studied the …

Molecular and functional characterization of human P2X2 receptors

KJ Lynch, E Touma, W Niforatos, KL Kage… - Molecular …, 1999 - ASPET
P2X receptors are a family of ATP-gated ion channels. Four cDNAs with a high degree of
homology to the rat P2X2 receptor were isolated from human pituitary and pancreas RNA …

Cloning of P2X5 and P2X6 receptors and the distribution and properties of an extended family of ATP-gated ion channels

G Collo, RA North, E Kawashima… - Journal of …, 1996 - Soc Neuroscience
Two new P2X receptor cDNAs (P2X5 and P2X6) were isolated and expressed. All six
proteins are 36–48 percent identical and seem to have two transmembrane segments with a …

Signaling at purinergic P2X receptors

A Surprenant, RA North - Annual review of physiology, 2009 - annualreviews.org
P2X receptors are membrane cation channels gated by extracellular ATP. Seven P2X
receptor subunits (P2X1-7) are widely distributed in excitable and nonexcitable cells of …
