Many multiprotein complexes mediate the fusion of the intracellular membranes. The question how the specificity of the membrane fusion is controlled has not been fully elucidated. Here we report the identification of a mouse homologue Vps16p (mVps16), which exhibits a high homology to the yeast Vps16p, a component of Class C vacuolar protein sorting (Vps) complex implicated in the yeast vacuole membrane fusion. Northern and Western blot analyses reveal that mVps16 is ubiquitously expressed in the mouse peripheral tissues. Biochemical analyses show that mammalian Class C Vps proteins interact with multiple syntaxins and Vps45p, which localizes in the endosomal compartments. The internalization of transferrin (Tf) is not affected by the overexpression of mammalian class C Vps proteins, but the recycling was inhibited. Taken together, this study provides biochemical characteristics of mVps16p in mammalian cells and the potential roles of mammalian Class C Vps proteins in membrane trafficking.
