Summation

GAPVD1 binds the alpha adaptin ear domain of AP-2 mu2, activating its RAB5-directed GEF activity and displacing AAK1. AAK1 displacement results in a net dephosphorylation of the AP-2 mu2 subunit, destabilizing the interaction of AP-2 with the vesicle membrane (Sato et al, 2005; Smerdjieva et al, 2008). In addition, RAB5 contributes to PI(4,5)P2 turnover through recruitment of a PI3K or PI phosphatase, and this also destabilizes the interaction of AP-2 with the membrane (Smerdjieva et al, 2008; Christoforidis et al, 1999; Shin et al, 2005).
