Abstract
The ‘free fatty acid receptor’ (FFAR) GPR41 strongly couples to ERK1/2 activation, while the coupling of GPR40 and GPR43 was weaker. JNK and p38MAPK were weakly activated by FFARs. All three receptors activated ERK1/2 fully or partially via Gi/o and Rac. PI3K was relevant for GPR40- and GPR41-mediated ERK1/2 activation, and Src was essential for GPR40- and GPR43-induced activation. Raf-1 was not involved in the GPR43-triggered activation. These results demonstrate that GPCRs belonging to the same family can regulate ERK1/2 activation by different receptor-specific mechanisms.
