s_mpk1_re62( Survival  map ):
The component kinases of the ERK cascade Raf-1 MEK and ERK assemble using beta-ARRESTIN as a scaffold and leading to activation of ERK. Endocytosis of these receptor/beta-ARRESTIN complexes by clathrin-coated pits results in the targeting of activated ERK to endosomal vesicles.
The beta-ARRESTIN occupied receptor undergoes internalisation into early endosomes. At the early endosome stage beta-ARRESTIN recruits both MEK1/2 and ERK1/2 and is likely to facilitate their activation upon GPCR stimulation.

s_mpk1_re86( Survival  map ):
The internalised GPCR receptor will finally be recycled into the cell membrane or be sent to lysosome for degradation (not modelled).
