Definition:

Olfactory receptor. Activated by the synthetic sandalwood odorant sandalore. Endogenous ligand is unknown (Probable). The activity of this receptor is probably mediated by G proteins which induce elevation of intracellular Ca(2+), a cAMP-dependent pathway and phosphorylation of MAPK1/ERK2, MAPK3/ERK1 and p38 MAPKs. Activation of OR2AT4 induces proliferation, migration, and re-epithelialization during wound-healing processes of keratinocytes. Stimulation of OR2AT4 by sandalore promotes hair growth by decreasing apoptosis and increasing production of the anagen-prolonging growth factor IGF1 as well as other pathways involving various kinases.
