RT autophagic turnover of plastids in Arabidopsis.";
RL Plant Cell 27:391-402(2015).
CC -!- FUNCTION: Involved in ESCRT-dependent multivesicular body (MVB)
CC formation and sorting of endosomal cargo proteins into MVBs. Mediates
CC the MVB sorting of the auxin carriers PIN1, PIN2 and AUX1. Required for
CC embryonic axis establishment and seedling growth (PubMed:19304934).
CC Required for autophagic degradation of plastid proteins. Promotes the
CC efficient sequestration of cargo from plastids into autophagosomes.
CC Mediates the efficient delivery of autophagic plastid bodies to the
CC vacuole, but not into the cytoplasm (PubMed:25649438).
CC {ECO:0000269|PubMed:19304934, ECO:0000269|PubMed:25649438}.
CC -!- SUBUNIT: Interacts with SKD1/VPS4 and LIP5 (PubMed:19304934,
CC PubMed:20663085). Interacts with CHMP1B (PubMed:20663085). Interacts
CC with VPS2.2 (PubMed:22010978). {ECO:0000269|PubMed:19304934,
CC ECO:0000269|PubMed:20663085, ECO:0000269|PubMed:22010978}.
CC -!- INTERACTION:
CC Q8LE58; Q0WTY4: VPS2.2; NbExp=4; IntAct=EBI-6391458, EBI-3865323;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9HD42}.
CC Endosome membrane {ECO:0000250|UniProtKB:Q9HD42}; Peripheral membrane
CC protein {ECO:0000250|UniProtKB:Q9HD42}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC conditions, but double mutants chmp1a and chmp1b show embryo
CC development defect. {ECO:0000269|PubMed:19304934}.
CC -!- SIMILARITY: Belongs to the SNF7 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAF99815.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
