Gene Name PTGER2
Uniprot ID PE2R2_HUMAN
KEGG Pathway hsa:5732
Protein Family G-protein coupled receptor 1 family
Protein Function
Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(s) proteins that stimulate adenylate cyclase. The subsequent raise in intracellular cAMP is responsible for the relaxing effect of this receptor on smooth muscle.
