+== Function ==
+[https://www.uniprot.org/uniprot/TS101_HUMAN TS101_HUMAN] Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Mediates the association between the ESCRT-0 and ESCRT-I complex. Required for completion of cytokinesis; the function requires CEP55. May be involved in cell growth and differentiation. Acts as a negative growth regulator. Involved in the budding of many viruses through an interaction with viral proteins that contain a late-budding motif P-[ST]-A-P. This interaction is essential for viral particle budding of numerous retroviruses.<ref>PMID:11916981</ref> <ref>PMID:17853893</ref> <ref>PMID:17556548</ref>

+== Publication Abstract from PubMed ==
+The UEV domain of the TSG101 protein functions in the vacuolar protein-sorting pathway and in the budding process of HIV-1 and other retroviruses by recognizing ubiquitin in proteins tagged for degradation and short sequences in viral proteins containing an essential and well conserved PTAP motif, respectively. A deep understanding of these interactions is key to the rational design of much-needed novel antivirals. Here, the crystal structure of the TSG101 UEV domain (TSG101-UEV) is presented. TSG101-UEV was crystallized in the presence of PEG 4000 and ammonium sulfate. Under these conditions, crystals were obtained in space group R3, with unit-cell parameters a = b = 97.9, c = 110.6 A, alpha = beta = 90, gamma = 120 degrees . Phases were solved by molecular replacement and the crystal structure of TSG101-UEV was refined to an R factor of 18.8% at 2.2 A resolution. A comparison between the crystal structure and previously reported NMR structures has revealed significant differences in the conformation of one of the loops implicated in ubiquitin recognition. Also, the resulting structure has provided information about the presence of water molecules at the binding interface that could be of relevance for peptide recognition.
