CC -!- FUNCTION: Multispanning membrane protein in the endoplasmic reticulum CC (ER) required for autophagosome formation (PubMed:30093494, CC PubMed:30933966, PubMed:28890335). Controls the disassociation of CC autophagosomes from the ER through its interaction with BECN1 and CC ATP2A2. Regulates ATP2A2 activity to control ER-isolation membrane CC contacts for autophagosome formation (PubMed:28890335). Also modulates CC ER contacts with lipid droplets, mitochondria and endosomes CC (PubMed:28890335). Required for lipoprotein secretion, involved in the CC release of lipoproteins from the ER membrane to the ER lumen CC (PubMed:31526472). Involved in cell-cell adhesion. Plays an essential CC role in formation of cell junctions (PubMed:17724469). Upon stress such CC as bacterial and viral infection, promotes formation of cytoplasmic CC vacuoles followed by cell death. Involved in the cytoplasmic CC vacuolization of acinar cells during the early stage of acute CC pancreatitis (By similarity). {ECO:0000250|UniProtKB:Q91ZQ0, CC ECO:0000269|PubMed:17724469, ECO:0000269|PubMed:28890335, CC ECO:0000269|PubMed:30093494, ECO:0000269|PubMed:30933966, CC ECO:0000269|PubMed:31526472}. CC -!- FUNCTION: (Microbial infection) Host factor required for infection by CC all flaviviruses tested such as Zika virus and Yellow fever virus CC (PubMed:33338421). Probably required post-entry of the virus to CC facilitate the ER membrane remodeling necessary to form replication CC organelles (PubMed:33338421). {ECO:0000269|PubMed:33338421}. CC -!- SUBUNIT: Interacts with BECN1 (By similarity). Interacts with TJP1 CC (PubMed:17724469). Interacts with TP53INP2 (PubMed:19056683). Interacts CC with TMEM41B (PubMed:30093494). Interacts with ATP2A2, PLN and SLN; CC competes with PLN and SLN to prevent them from forming an inhibitory CC complex with ATP2A2 (PubMed:28890335). {ECO:0000250|UniProtKB:Q91ZQ0, CC ECO:0000269|PubMed:17724469, ECO:0000269|PubMed:19056683, CC ECO:0000269|PubMed:28890335, ECO:0000269|PubMed:30093494}.
