== Publication Abstract from PubMed ==

The ESCRT-0 and ESCRT-I complexes coordinate the clustering of ubiquitinated cargo with intralumenal budding of the endosomal membrane, two essential steps in vacuolar/lysosomal protein sorting from yeast to humans. The 1.85-A crystal structure of interacting regions of the yeast ESCRT-0 and ESCRT-I complexes reveals that PSDP motifs of the Vps27 ESCRT-0 subunit bind to a novel electropositive N-terminal site on the UEV domain of the ESCRT-I subunit Vps23 centred on Trp16. This novel site is completely different from the C-terminal part of the human UEV domain that binds to P(S/T)AP motifs of human ESCRT-0 and HIV-1 Gag. Disruption of the novel PSDP-binding site eliminates the interaction in vitro and blocks enrichment of Vps23 in endosome-related class E compartments in yeast cells. However, this site is non-essential for sorting of the ESCRT cargo Cps1. Taken together, these results show how a conserved motif/domain pair can evolve to use strikingly different binding modes in different organisms.

[[http://www.uniprot.org/uniprot/STP22_YEAST STP22_YEAST]] 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 to the ESCRT-0 complex. Required for vacuolar targeting of temperature-sensitive plasma membrane proteins STE2 and CAN1.<ref>PMID:10207082</ref> <ref>PMID:11208108</ref> <ref>PMID:11511343</ref> [[http://www.uniprot.org/uniprot/VPS27_YEAST VPS27_YEAST]] Component of the ESCRT-0 complex which is the sorting receptor for ubiquitinated cargo proteins at the multivesicular body (MVB) and recruits ESCRT-I to the MVB outer membrane. Controls exit from the prevacuolar compartment (PVC) in both the forward direction to the vacuole and the return to the Golgi. Allows VPS10 to return to the (trans-Golgi network) TGN from the PVC. Might also function as an alternate adapter in the COPIb clathrin-like coat.<ref>PMID:3062374</ref> <ref>PMID:1493335</ref> <ref>PMID:8649377</ref> <ref>PMID:9015300</ref> <ref>PMID:9265642</ref> <ref>PMID:11208109</ref> <ref>PMID:11416128</ref> <ref>PMID:12055639</ref> <ref>PMID:11872141</ref> <ref>PMID:12900393</ref> <ref>PMID:14581452</ref> <ref>PMID:15166140</ref> <ref>PMID:15107463</ref> <ref>PMID:15086794</ref> <ref>PMID:17101773</ref> <ref>PMID:17135292</ref>
