Homologous Superfamily

HIV-1 Nef protein, core domain superfamily (IPR027481)

Short name: HIV-1_Nef_core_sf

Overlapping entries


Human immunodeficiency virus 1 (HIV-1) negative factor (Nef protein) accelerates virulent progression of acquired immunodeficiency syndrome (AIDS) by its interaction with specific cellular proteins involved in signal transduction and host cell activation. Nef has been shown to bind specifically to a subset of the Src family of kinases [PMID: 9351809].

Negative factor (Nef) has a two-domain structure consisting of an N-terminal anchor domain and a core domain separated by a specific cleavage site of the HIV proteases. The N-terminal domain is not compactly folded and constitutes a mobile membrane anchor and a linker to the core domain [PMID: 8174561, PMID: 10339411].
