physiological function | the HIV-1 accessory protein Nef is N-terminally myristoylated and this posttranslational modification is essential for Nef function in AIDS progression, Nef has no known catalytic activity but rather binds to a number of host-cell proteins. Transfer of a myristate group from myristoyl coenzyme A to Nef occurs cotranslationally and is catalyzed by human N-myristoyl transferase-1. Myristoylated Nef adopts a different tertiary and quaternary structure than non-myristoylated Nef, but conformational changes in Nef are no result of myristoylation, overview. NMT might chaperone Nef to the membrane and thereby protect the myristic acid group from the cytosol rather than Nef operating through a myristic acid switch mechanism | Homo sapiens |
