Structural highlightsFunctionTM87A_HUMAN May be involved in retrograde transport from endosomes to the trans-Golgi network (TGN) (PubMed:26157166). In one study, shown to be a component of a novel mechanoelectrical transduction pathway which is involved in cell adhesion and migration, and is thought to act either as a mechanically activated ion channel or as an accessory protein which modulates an unidentified mechanically activated ion channel (PubMed:32228863). In another study, neither basal nor mechanically activated channel activity has been observed and, based on structural similarity with WLS, has been suggested to function as a trafficking chaperone for membrane-associated cargo (PubMed:36373655).[1] [2] [3]
