Description:
Recombinant myristoylated signalling-defective mutant HIV-1 Nef protein (myr2-210, C210S, PxxPxP to AxxAxA) with a C-terminal His6-tag. Human immunodeficiency virus type 1 (HIV-1) Nef is a membrane-associated protein that is produced at an early stage of viral gene expression and is a component of viral particles. Nef has been demonstrated to bind and downregulate cell-surface receptors CD4, MHC class I and II molecules and DCSIGN. A Nef mutant with simple alanine substitutions at the myristoylation and dileucine sites was impaired in its ability to elicit Nef-specific CD4(+) and CD8(+) T cell responses. In addition, Nef has been reported to have diverse effects on cellular signal transduction pathways. It interacts with various cellular protein kinases and acts both as a kinase substrate and as a modulator of kinase activity.
