Introduction

OUTLINE FOR INTRODUCTION:

A)P2Y receptors are a subunit of a catergory of purinergic G-protein-coupled receptors

Cell receptors have specificity for ATP or ADP over adenosine P2Y12-->platelet activation and thrombus formation Drugs Candidates - engineered molecules (allosteric regulators) that can inhibit P2Y12 receptors through conformational change and active site inhibition. B) Plavix, Effient, and Brilinta

Effects on P2Y12

C)ADZ1283 - Binding and Pocket Chemistry D) Differences between P2Y12r with and without ADZ1283

Note: Green Scene still to come

Overall Structure

-Secondary Structure: 

The is made up of eight alpha helices. There are seven transmembrane alpha helices and a carboxy-terminal helix VII, which is parallel to the membrane bilayer. Only one disulphide bond the amino terminus with helix VII

- Polar vs nonpolar:

Polar regions are pink. Nonpolar, or hydrophobic, regions are grey.

-N to C termini:

The protein shown in displays the the N and C termini

Binding Interactions

The of P2Y12 is colored in purple, which is the buried site, along with the ligands, which is colored in yellow.
