Mediates docking of ADAM10 to zonula adherens by interacting with PLEKHA7 which is required for PLEKHA7 to interact with the ADAM10-binding protein TSPAN33. Interacts with ATP2B1, ATP2B2, ATP2B3, ATP2B4 and ATP7A (By similarity). Interacts with PLEKHA7 (via WW domains) at zonula adherens; this interaction is essential for the interaction between PLEKHA7 and the ADAM10-binding protein TSPAN33 (By similarity). Interacts with SLC5A6 (By similarity).
