Description | Vps36 is a subunit of ESCRT-II, a protein complex involved in driving protein sorting from endosomes to lysosomes. The GLUE domain of Vps36 allows for a tight interaction to occur between the protein and Vps28, a subunit of ESCRT-I. This interaction is critical for ubiquitinated cargo progression from early to late endosomes [ ]. The multivesicular body (MVB) protein-sorting pathway targets transmembrane proteins either for degradation or for function in the vacuole/lysosomes. Thesignal for entry into this pathway is monoubiquitination of protein cargo, which results in incorporation of cargo into luminal vesicles at lateendosomes. Another crucial player is phosphatidylinositol 3-phosphate (PtdINS(3)P), which is enriched on early endosomes and on the luminal vesiclesof MVBs. ESCRT (endosomal sorting complex required for transport)-I, -II and -III complexes are critical for MVB budding and sorting of monoubiquitinated cargo into the luminal vesicles []. Various Ub-binding domains(UBDs), such as UIM, UEV and NZF are found in such machineries [, ].The Vps 36 subunit of the ESCRT-II trafficking complex binds both phosphoinositides and ubiquitin. All members of the Vps36 family contain adivergent GRAM/PH-like domain; yeast and some other fungi have one or two NZF domains inserted in the GRAM/PH-like domain [, ]. |
