G βγ recruits and activates P-Rex1 via two independent binding interfaces.
In conclusion, we reconcile previous findings and propose a mechanistic model of P-Rex1 activation; accordingly, Gβγ recruits P-Rex1 via the Gβγ/PDZ-PDZ interface followed by a second contact involving the Gβγ/DH/PH interface to unleash P-Rex1 RacGEF activity at the plasma membrane.
