DT 9408 AU Bandres JC; Luria S; Ratner L; Department of Medicine, Washington University School of Medicine,; St. Louis, Missouri. SO Virology. 1994 May 15;201(1):157-61. Unique Identifier : AIDSLINE MED/94233766 AB Human immunodeficiency virus isolates express a Nef protein with either an alanine or a threonine at amino acid residue 15. The threonine residue is a site for phosphorylation by protein kinase C. Jurkat T cells constitutively expressing the alanine variant of Nef exhibit the ability to downregulate the induction of transcription factors NF-kB and AP-1. In contrast, Jurkat cells with the threonine variant of Nef are at least partially restored in their ability to recruit NF-kB and AP-1.
