== Function ==
[[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/SRN2_YEAST SRN2_YEAST]] Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Required for normal endocytic and biosynthetic traffic to the yeast vacuole. [[http://www.uniprot.org/uniprot/VPS28_YEAST VPS28_YEAST]] Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Required for normal endocytic and biosynthetic traffic to the yeast vacuole.

== Publication Abstract from PubMed ==
The endosomal sorting complex required for transport (ESCRT) complexes are central to receptor downregulation, lysosome biogenesis, and budding of HIV. The yeast ESCRT-I complex contains the Vps23, Vps28, and Vps37 proteins, and its assembly is directed by the C-terminal steadiness box of Vps23, the N-terminal half of Vps28, and the C-terminal half of Vps37. The crystal structures of a Vps23:Vps28 core subcomplex and the Vps23:Vps28:Vps37 core were solved at 2.1 and 2.8 A resolution. Each subunit contains a structurally similar pair of helices that form the core. The N-terminal domain of Vps28 has a hydrophobic binding site on its surface that is conformationally dynamic. The C-terminal domain of Vps28 binds the ESCRT-II complex. The structure shows how ESCRT-I is assembled by a compact core from which the Vps23 UEV domain, the Vps28 C domain, and other domains project to bind their partners.
