The COPII-COPI-protein switch is necessary for maturation of the vesicular-tubular cluster, VTC, intermediate compartments for Golgi compartment biogenesis. This N-terminal domain however does not appear to be binding either of the COP or the ARF [2]. This is the HUS (homology upstream of Sec7) domain of Sec7 and related proteins such as protein Mon2 and BIG1-like proteins, which plays a regulatory role [3,4] together with DCB domain (Pfam:PF16213).
