Taxonomic identifier

9606 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	342 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Receptor for ADP and ATP coupled to G-proteins that inhibit the adenylyl cyclase second messenger system. Not activated by UDP and UTP. Involved in platelets aggregation.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Highly expressed in the platelets, lower levels in the brain. Lowest levels in the lung, appendix, pituitary and adrenal gland. Expressed in the spinal cord and in the fetal brain.
Involvement in disease	Defects in P2RY12 are the cause of bleeding disorder platelet-type 8 (BDPLT8) [MIM:609821]. A condition characterized by mild to moderate mucocutaneous bleeding, and excessive bleeding after surgery or trauma. The defect is due to severe impairment of platelet response to ADP resulting in defective platelet aggregation. Ref.1 Ref.10
Sequence similarities	Belongs to the G-protein coupled receptor 1 family.
