The HIV Nef protein downregulates CD4 through sequential connection with clathrin-coated pits and the COP1 coatomer, resulting in accelerated endocytosis and lysosomal targeting. The small GTPase ARF1 controls the Nef-induced, COP-mediated late-endosomal targeting of CD4. Nef binds ARF1 directly and can recruit the GTPase onto endosomal membranes, leading to the eventual degradation of CD4 (Faure et al. 2004).
