May be involved in the cytoplasmic vacuolization of acinar cells during the early stage of acute pancreatitis. Plays a role in the initial stages of the autophagic process through its interaction with BECN1. Involved in cell-cell adhesion. Plays an essential role in formation of cell junctions. Interacts with BECN1. Interacts with TJP1. Interacts with TP53INP2. Belongs to the VMP1 family. Note: This description may include information from UniProtKB.
