We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Publication Abstract from PubMed
VHS (Vps27, Hrs, and STAM) domains occur in ESCRT-0 subunits Hrs and STAM, GGA adapters, and other trafficking proteins. The structure of the STAM VHS domain-ubiquitin complex was solved at 2.6 A resolution, revealing that determinants for ubiquitin recognition are conserved in nearly all VHS domains. VHS domains from all classes of VHS-domain containing proteins in yeast and humans, including both subunits of ESCRT-0, bound ubiquitin in vitro. ESCRTs have been implicated in the sorting of Lys63-linked polyubiquitinated cargo. Intact human ESCRT-0 binds Lys63-linked tetraubiquitin 50-fold more tightly than monoubiquitin, though only 2-fold more tightly than Lys48-linked tetraubiquitin. The gain in affinity is attributed to the cooperation of flexibly connected VHS and UIM motifs of ESCRT-0 in avid binding to the polyubiquitin chain. Mutational analysis of all the five ubiquitin-binding sites in yeast ESCRT-0 shows that cooperation between them is required for the sorting of the Lys63-linked polyubiquitinated cargo Cps1 to the vacuole.
