Once loaded the vesicles become fully sculpted, pinch off from the ER and bud into the cytosol. Budding depends on SAR1:GTPase activity and likely releases the SEC16 complex. SAR1:GTPase activity may result in partial uncoating of the emerging vesicle, allowing SEC23 to be exposed for subsequent TRAPPCII binding.
