P2Y Receptor Expressing Human Astrocytoma Cell Lines
1321N1 human astrocytoma cell lines expressing various P2Y purinergic G protein-coupled receptors.
Highlights:
- Available expressing one of the following: P2Y1, P2Y4, P2Y11, P2Y12
- Distinguished from most other cultured cell lines in that native 1321N1 cells have no response to extracellular nucleotides
- Most other cell lines express one or more P2Y receptors, making them problematic for screening or assessing receptor function
Astrocytomas are a type of cancer of the brain. They originate in a particular kind of glial cells, star-shaped brain cells in the cerebrum called astrocytes. This type of tumor does not usually spread outside the brain and spinal cord and it does not usually affect other organs. P2Y receptors are a family of purinergic G protein coupled receptors that are stimulated by nucleotides.

Comments
Receptor Information:
- The P2Y1 receptor couples to Gq and is important in ADP-mediated platelet aggregation and activated by ADP
- The P2Y4 receptor is coupled to Gq and activated by UTP; the human receptor is antagonized by ATP
- The P2Y11 receptor is activated by ATP and couples to Gq and Gs, although the coupling to Gq occurs at lower concentration of agonist
- The P2Y12 receptor is important in platelet aggregation and is the target of clopidogrel and other platelet inhibitors; The receptor coupels to Gi
