Detection of human immunodeficiency virus type 1 Nef and CD4 physical interaction in living human cells by using bioluminescence resonance energy transfer.

چکیده
CD4 down-regulation by human immunodeficiency virus type 1 (HIV-1) Nef protein is a key function for virus virulence. This activity may be mediated by a direct Nef-CD4 interaction. We investigated the formation, in situ, of such a complex between proteins using bioluminescence resonance energy transfer technology and co-immunoprecipitations. Our data clearly demonstrate that Nef and CD4 interact in intact human cells. Moreover, our results clearly indicate that the dileucine motif of the CD4 cytoplasmic domain, critical for the Nef-induced CD4 down-regulation, is not implicated in the Nef/CD4 complex formation in the cellular context.

Downregulation of CD4 by human immunodeficiency virus type 1 Nef is dependent on clathrin and involves direct interaction of Nef with the AP2 clathrin adaptor.
Nef, an accessory protein of human and simian immunodeficiency viruses, is a critical determinant of pathogenesis that promotes the progression from infection to AIDS. The pathogenic effects of Nef are in large part dependent on its ability to downregulate the macrophage and T-cell coreceptor, CD4. It has been proposed that Nef induces downregulation by linking the cytosolic tail of CD4 to comp...
متن کاملHuman immunodeficiency virus type 1 Nef and p56lck protein-tyrosine kinase interact with a common element in CD4 cytoplasmic tail.
The human immunodeficiency virus type 1 nef gene induces endocytosis of CD4 antigen and disrupts the association between CD4 and p56lck protein-tyrosine kinase (EC 2.7.1.112). We demonstrate that in T cells these effects of the viral protein require a cluster of hydrophobic amino acids in a membrane-proximal region of the CD4 cytoplasmic tail; other amino acids in the C-terminal segment of CD4 ...

متن کاملCD4 down-modulation by human immunodeficiency virus type 1 Nef correlates with the efficiency of viral replication and with CD4(+) T-cell depletion in human lymphoid tissue ex vivo.
The human immunodeficiency virus type 1 (HIV-1) Nef protein is an important virulence factor. Nef has several functions, including down-modulation of CD4 and class I major histocompatibility complex cell surface expression, enhancement of virion infectivity, and stimulation of viral replication in peripheral blood mononuclear cells. Nef also increases HIV-1 replication in human lymphoid tissue ...
متن کاملNef-induced CD4 endocytosis in human immunodeficiency virus type 1 host cells: role of p56lck kinase.
Human immunodeficiency virus type 1 (HIV-1) Nef interferes with the endocytic machinery to modulate the cell surface expression of CD4. However, the basal trafficking of CD4 is governed by different rules in the target cells of HIV-1: whereas CD4 is rapidly internalized from the cell surface in myeloid cells, CD4 is stabilized at the plasma membrane through its interaction with the p56(lck) kin...
