Status
Functioni
Endosomal sorting complex required for transport (ESCRT) component regulating multivesicular body (MVB) protein sorting and plant growth (PubMed:25438943). Required for the formation of intra-luminal vesicles (ILVs)in MVBs (PubMed:25438943). Binds to phosphatidylinositol-3-phosphate (PI3P) and ubiquitin (PubMed:25438943, PubMed:24843126). Controls IRT1 recycling to the plasma membrane and impacts the polar delivery of this transporter to the outer plasma membrane domain (PubMed:24843126). Regulates ubiquitin-dependent membrane protein degradation, vacuolar transport, autophagy, and vacuole biogenesis (PubMed:25699591, PubMed:25624505).4 Publications
