We have previously shown that NF-κB nuclear translocation can be observed upon human immunodeficiency virus type 1 (HIV-1) binding to cells expressing the wild-type CD4 molecule, but not in cells expressing a truncated form of CD4 that lacks the cytoplasmic domain (M. Benkirane, K.-T. Jeang, and C. Devaux, EMBO J. 13:5559–5569, 1994). This result indicated that the signaling cascade which controls HIV-1-induced NF-κB activation requires the integrity of the CD4 cytoplasmic tail and suggested the involvement of a second protein that binds to this portion of the molecule. Here we investigate the putative role of p56lck as a possible cellular intermediate in this signal transduction pathway. Using human cervical carcinoma HeLa cells stably expressing CD4, p56lck , or both molecules, we provide direct evidence that expression of CD4 and p56lck is required for HIV-1-induced NF-κB translocation. Moreover, the fact that HIV-1 stimulation did not induce nuclear translocation of NF-κB in cells expressing a mutant form of CD4 at position 420 (C420A) and the wild-type p56lck indicates the requirement for a functional CD4-p56lck complex.
