The Nef protein of Human Immunodeficiency Virus (HIV) and Simian Immunodeficiency Virus (SIV) is a pluripotent accessory protein that plays a critical role in disease progression. One analogous characteristic of Nef proteins from SIV and HIV is the ability to associate with cellular kinases. We have previously reported that the Nef protein from a macrophage-tropic neurovirulent SIV clone, SIV/17E-Fr, is associated with an unknown kinase activity that is distinct from the p21-associated kinase that interacts with SIVmac239 Nef. Using site-directed mutagenesis and kinase-specific inhibitors, we have identified this kinase as the ubiquitous serine/threonine kinase, protein kinase CK2.
