SO Eur J Biochem. 1994 Jul 15;223(2):589-93. Unique Identifier : AIDSLINE GENBANK AB Negative factor (Nef) protein from human immunodeficiency virus type 1 (HIV-1) is cleaved into two well-defined domains by the HIV-1-encoded protease. The cleavage site is located between Trp57 and Leu58 and is well conserved. The two domains are stable in the presence of protease for more than 48 h. The C-terminal core domain contains a well-conserved well-folded region. The cleavage releases the core domain from the myristoylated membrane anchor domain. As is the case for other HIV proteins, cleavage of Nef could be crucial for correct biological function.
