Thr-96 and Ser-165 are phosphorylated by the mitogen activated kinase MAP4K1. As the HIV-1 replication can be activated by stress and mitogens, these phosphorylations could be involved in this process. Ser-144 phosphorylation may inhibit elongin BC complex binding.MISCELLANEOUS Required for replication in 'nonpermissive' cells, including primary T-cells, macrophages and certain T-cell lines, but is dispensable for replication in 'permissive' cell lines, such as 293T cells. In nonpermissive cells, Vif-defective viruses can produce virions, but they fail to complete reverse transcription and cannot successfully infect new cells.MISCELLANEOUS Vif-defective viruses show catastrophic failure in reverse transcription due to APOBEC-induced mutations that initiate a DNA base repair pathway and compromise the structural integrity of the ssDNA. In the absence of Vif, the virion is morphologically abnormal.MISCELLANEOUS The infectious clone pNL4-3 is a chimeric provirus that consists of DNA from HIV isolates NY5 (5' half) and BRU (3' half).MISCELLANEOUS HIV-1 lineages are divided in three main groups, M (for Major), O (for Outlier), and N (for New, or Non-M, Non-O). The vast majority of strains found worldwide belong to the group M. Group O seems to be endemic to and largely confined to Cameroon and neighboring countries in West Central Africa, where these viruses represent a small minority of HIV-1 strains. The group N is represented by a limited number of isolates from Cameroonian persons. The group M is further subdivided in 9 clades or subtypes (A to D, F to H, J and K).SIMILARITY Belongs to the primate lentivirus group Vif protein family. | lld:biopax3 |
