Epithelial membrane protein 2 (EMP2)

Functions as a key regulator of cell membrane composition by regulating proteins surface expression. Additionally, it plays a role in regulation of processes such as cell migration, cell proliferation, cell contraction and cell adhesion.

Negatively regulates caveolae formation by reducing CAV1 expression and CAV1 amount by raising lysosomal degradation (PubMed:24814193). Facilitates surface trafficking and formation of lipid rafts bearing GPI-anchor proteins (By similarity).
