Description
Product Characteristics: Nef (Negative Regulatory Factor) is a protein expressed by primate lentiviruses. These include human immunodeficiency viruses (HIV-1 and HIV-2) and simian immunodeficiency virus (SIV). Nef is one of many pathogen-expressed proteins, known as virulence factors, which function to manipulate the host's cellular machinery and thus allow infection, survival or replication of the pathogen. Nef stands for Negative Factor. Synonyms: Monoclonal HIV1 Nef antibody, Anti-HIV1 Nef antibody, HIV-1 Nef antibody, 3'ORF antibody, ABIN antibody, ABIN1 antibody,C terminal core protein antibody, F protein antibody, Nef antibody, Negative factor antibody, p27 antibody, VAN antibody.
Target Information: Seems to play a role in optimizing the host cell environment for viral replication without causing cell death by apoptosis. Enhances virus infectivity and pathogenicity. Probably involved in viral immune evasion mechanisms (By similarity). {ECO:0000250}. In infected CD4(+) T-lymphocytes, down-regulates cell surface expression of CD4, CD28, CD3, and MHC-I or MHC-II molecules. {ECO:0000250}. Interferes with TCR signaling from the cell membrane. Interacts with CD247/TCRZ (TCR zeta chain) and exert potent down- regulation of cell surface TCR/CD3 complexes (By similarity). {ECO:0000250}
