Antagonist Comments
It is likely that ATP and derivatives (e.g., 2-ClATP and 2MeSATP) act as antagonist at P2Y1 rather than agonists. The apparent agonist action of these compounds may be due to impurity and to the rapid conversion to the diphosphate form [22]. High-throughput screening against the P2Y1 receptor identified a novel series of tetrahydro-4-quinolinamine antagonists [36].

Biologically Significant Variants
A silent polymorphism in the coding seguence of the P2Y1 gene is associated with different platelet reactivity to ADP
Type:  Single nucleotide polymorphism
Species:  Human
References:  23
The presence of a polymorphism appears to confer an attenuated antiplatelet effect during aspirin treatment in healthy Chinese subjects

General Comments
In all species, the P2Y1 receptor is selective for adenine nucleotides. Presence of P2Y1 receptors has been reported in mitochondria of astrocytes and C6 cells, although its role in these sub-cellular structures remains unclear [29].
