B, C	PF12932	Vesicle coat trafficking protein Sec16 mid-region (Sec16)	Vesicle coat trafficking protein Sec16 mid-region	Sec16 is a multi-domain vesicle coat protein. This central region is the functional part of the molecules and thus is vital for the family's role in mediating the movement of protein-cargo between the organelles of the secretory pathway [1].	Domain
B, C	PF12931	Sec23-binding domain of Sec16 (Sec16_C)	Sec23-binding domain of Sec16	Sec16 is a multi-domain vesicle coat protein. The C-terminal region is the part that binds to Sec23, a COPII vesicle coat protein. This association is part of the transport vesicle coat structure [1].	Domain
