To accomplish this, Nef interacts with a series of cellular partners including CD4, components of the adaptor complexes AP-1 and AP-2, and several protein kinases, Nef often functioning as a connector between targets and effectors.

Furthermore, altered functional domains were noted in several isolates, such as the cAMP-dependent kinase PKA phosphorylation site in Nef (LT5), a Vpr mutation involved in decreased proapoptotic activity (all isolates), and the Nef ExxxLL motif involved in the interaction with AP-1 and AP-2 (LT46).
