At the beginning of this reaction, 4 molecules of 'ATP', and 1 molecule of 'GRB2:SOS:IRS-P' are present. At the end of this reaction, 1 molecule of 'GRB2:IRS-P', 1 molecule of 'phospho-SOS', and 4 molecules of 'ADP' are present.

This reaction takes place on the 'internal side of plasma membrane' and is mediated by the 'kinase activity' of 'ERK1'.
