Protein Domain : Vacuolar protein sorting-associated Vps28 IPR007143

Type  Family
Description  The Endosomal Sorting Complex Required for Transport (ESCRT) complexes form the machinery driving protein sorting from endosomes to lysosomes. ESCRT complexes are central to receptor down-regulation, lysosome biogenesis, and budding of HIV. Yeast ESCRT-I consists of three protein subunits, Vps23, Vps28, and Vps37. In humans, ESCRT-I comprises TSG101, VPS28, and one of four potential human VPS37 homologues. The main role of ESCRT-I is to recognise ubiquitinated cargo via the UEV domain of the VPS23/TSG101 subunit. The assembly of the ESCRT-I complex is directed by the C-terminal steadiness box (SB) of VPS23, the N-terminal half of VPS28, and the C-terminal half of VPS37. The structure is primarily composed of three long, parallel helical hairpins, each corresponding to a different subunit. The additional domains and motifs extending beyond the core serve as gripping tools for ESCRT-I critical functions [ , ].
