Question
Which of the following is incorrect?
COPII coated vesicles require Sar1 bound to GTP to bind to recruit COPII proteins
COPII coated vesicles require a GEF called Sec12
COPII coated vesicles require Arf bound to GTP to recruit Sec23/24
CopII coated vesicles require clathrin to assemble on the cytosolic side of the vesicles
COPII coated vesicles require Sar1 bound to GTP to bind to recruit COPII proteins
COPII coated vesicles require a GEF called Sec12
COPII coated vesicles require Arf bound to GTP to recruit Sec23/24
CopII coated vesicles require clathrin to assemble on the cytosolic side of the vesicles
Explanation / Answer
COPII coated vesicles require Arf bound to GTP to recruit Sec23/24
The Sec23–Sec24 heterodimer is recruited directly by activated Sar1
