protein
| binding directly to ARP1 (ACTR1A, ACTR1B) |
|
interacting with ATP7B (key component of the copper-induced trafficking pathway that delivers ATP7B to subapical vesicles of hepatocytes for the removal of excess copper into bile), interaction required copper, the metal-binding CXXC motifs, and the region between MBS 4 and MBS 6 of ATP7B  |
|
interacting with ANK2 (ANK2 is required for the costamere localization of DCTN4 and is a candidate to mediate interactions of DCTN4 with membrane cargo as well as to stabilize the fast-growing ends of specialized microtubules associated with costameres)  |
|
ANK2 binds to dystrophin, DCTN4, and microtubules and is required for sarcolemmal association of these proteins as well as dystroglycan  |
