This family contains various proteins that are homologs of the yeast Vps54 protein, such as the rat homolog (Swiss:Q9JMK8), the human homolog (Swiss:Q86YF7), and the mouse homolog (Swiss:Q8R3X1). In yeast, Vps54 associates with Vps52 and Vps53 proteins to form a trimolecular complex that is involved in protein transport between Golgi, endosomal, and vacuolar compartments [1]. All Vps54 homologs contain a coiled coil region (not found in the region featured in this family) and multiple dileucine motifs [1].
