CC -!- FUNCTION: Phospholipid scramblase involved in lipid homeostasis and
CC membrane dynamics processes. Has phospholipid scramblase activity
CC toward cholesterol and phosphatidylserine, as well as
CC phosphatidylethanolamine and phosphatidylcholine. Required for
CC autophagosome formation: participates in early stages of autophagosome
CC biogenesis at the endoplasmic reticulum (ER) membrane by
CC reequilibrating the leaflets of the ER as lipids are extracted by ATG2
CC (ATG2A or ATG2B) to mediate autophagosome assembly. Regulates ATP2A2
CC activity to control ER-isolation membrane contacts for autophagosome
CC formation. In addition to autophagy, involved in other processes in
CC which phospholipid scramblase activity is required. Modulates ER
CC contacts with lipid droplets, mitochondria and endosomes. Plays an
CC essential role in formation of cell junctions (By similarity). Upon
CC stress such as bacterial and viral infection, promotes formation of
CC cytoplasmic vacuoles followed by cell death. Involved in the
CC cytoplasmic vacuolization of acinar cells during the early stage of
CC acute pancreatitis (By similarity). {ECO:0000250|UniProtKB:Q91ZQ0,
CC ECO:0000250|UniProtKB:Q96GC9}.

CC -!- SUBUNIT: Interacts with BECN1 (By similarity). Interacts with TJP1.
CC Interacts with TP53INP2. Interacts with TMEM41B. Interacts with ATP2A2,
CC PLN and SLN; competes with PLN and SLN to prevent them from forming an
CC inhibitory complex with ATP2A2. Interacts with ATG2A (By similarity).
CC {ECO:0000250|UniProtKB:Q91ZQ0, ECO:0000250|UniProtKB:Q96GC9}.

CC compartment membrane {ECO:0000250|UniProtKB:Q91ZQ0}; Multi-pass
CC membrane protein {ECO:0000255}. Cell membrane
CC {ECO:0000250|UniProtKB:Q96GC9}; Multi-pass membrane protein
CC {ECO:0000255}. Vacuole membrane {ECO:0000250|UniProtKB:Q91ZQ0}; Multi-
CC pass membrane protein {ECO:0000255}. Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q96GC9}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- DOMAIN: The VTT domain was previously called the SNARE-assoc domain. As
CC there is no evidence that this domain associates with SNARE proteins,
CC it was renamed as VMP1, TMEM41, and TVP38 (VTT) domain.
CC {ECO:0000250|UniProtKB:Q96GC9}.
CC -!- SIMILARITY: Belongs to the VMP1 family. {ECO:0000305}.
