(a) PAR2-mediated ERK1/2 activity. KNRK-PAR2 (⋄) and KNRK-PAR2(δST363/6A) (▴) cells were treated with 50 nM trypsin for 0–30 min, and ERK activity was measured using the MBP assay. (b) Activation of ERK1/2. KNRK-PAR2(δST363/6A) (▴), KNRK-PAR2 (δST363/6A)+ARR-GFP (▵), and KNRK-PAR2 (δST363/6A)+ARR^319-418-GFP (♦) cells were treated with 50 nM trypsin for 0–30 min and phosphorylation was assessed using antibodies to pERK1/2. *P < 0.05 compared with KNRK-PAR2 cells, n = 3.
