P2RY4

A gene on chromosome Xq13 that encodes a subfamily of G protein-coupled receptors, which acts as a receptor for uridine and partially for ATP. It is not responsive to ADP.

There are eight subtypes of P2Y receptors (P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14), which are ubiquitously expressed in body, including the CNS [32].

The first evidence relating purinergic receptor and fibrosis showed the presence of functional P2Y2, P2Y4, and P2Y6 receptors in both quiescent and activated HSCs [130].
ATP and UTP are vasoactive signals able to increase [[[Ca.sup.2+]].sub.i] in the retina, via stimulation of purinergic receptors including P2Y4 [4].
Eight subtypes of P2Y have been identified to date--P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14--with differences in both pharmacology and downstream signalling pathways [3, 4].
UTP is only known to activate P2Y2, P2Y4, and P2Y6 receptors [23], and, of these, the only receptor responsive to ATP is P2Y2.
Furthermore, both UTP[gamma]S (P2Y2 and P2Y4 selective agonist) and 2-thio-UTP (P2Y2 selective) could induce CCL2 secretion above basal levels but not to the same degree as UTP (full agonist at P2Y2).
There are seven known P2X receptor subtypes (P2X1-7) and eight P2Y receptor subtypes (P2Y1, P2Y2, p2y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14) [31].

At present, there are eight accepted P2Y receptors: P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13, and P2Y14 [8, 9].
Antibodies against P2Y2, P2Y4, and P2Y6 receptors were from Alomone Labs (Jerusalem, Israel) and other antibodies were from Santa Cruz Biotech (Santa Cruz, CA, USA), from Cell Signaling (Danvers, MA, USA), or from the sources previously described [22].
The TaqMan probes for mouse EP1, EP2, EP3, EP4, P2Y2, and P2Y4 used in this study were purchased from Applied Biosystems and experiments for validation of amplification efficiency were performed for each TaqMan probe set [28, 29].
