This domain family is found in eukaryotes, and is approximately 50 amino acids in length. Vps 11 is one of the evolutionarily conserved class C vacuolar protein sorting genes (c-vps: vps11, vps16, vps18, and vps33), whose products physically associate to form the c-vps protein complex required for vesicle docking and fusion.
