FIGURE 9:

Regulators of ATP7A trafficking. Schematic representation of the proposed trafficking routes taken by endogenous ATP7A, either constitutively (left) or induced by copper level changes (right). Routes are marked by arrows, and blocks imposed by RNAi, mutant constructs, or drug treatment are shown (see also Table 1). Putative involvement of AP-2 in the constitutive pathway is shown as (?) (see the text). AP180-C shows a similar phenotype to clathrin knockdown and is not included in the scheme. Rab22aQ64L expression causes disruption of the TGN, which is not illustrated. Copper-induced forward pathway is shown as a direct trafficking step to the PM, although intermediary vesicles might be involved as in the constitutive route. V, vesicle.
