GPR55 Rabbit anti-Human, Polyclonal, Proteintech

G-protein Coupled Receptors (GPCRs) comprise one of the largest families of signaling molecules with more thana thousandmembers currently predicted to exist. All GPCRs share a structural motif consisting of seven membrane-spanning helices, and exist in both active and inactive forms. An array of activating ligands participate in the conformation of GPCRs which leads to signaling via G-proteins and downstream effectors. Ongoing studies have also shown the vast series of reactions which participate in the negative regulation of GPCRs. This "turn-off" activity has tremendous implications for the physiological action of the cell, and continues to drive pharmacological research for new drug candidates. .
