 AB    With T-cell lines constitutively expressing Nef from the SF2 strain of
       human immunodeficiency virus type 1 (HIV-1SF2) in the form of a hybrid
       CD8-Nef fusion protein or T-cell lines chronically infected with
       HIV-1SF2, a cellular serine kinase was found that specifically
       associates with Nef. Proteins of 62 kDa and 72 kDa, which
       coimmunoprecipitated with Nef, were phosphorylated in in vitro kinase
       assays. This Nef-associated serine kinase activity was not blocked by
       inhibitors of protein kinase C or protein kinase A and was lost when Nef
       was truncated at amino acid 94 or 99. These findings present evidence
       that a serine kinase activity is associated with Nef expressed in human
       T lymphocytes.
