The C. elegans vitellogenin genes: short sequence repeats in the promoter regions and homology to the vertebrate genes.

abstract：:The HIV-1 viral infectivity factor (Vif) allows productive infection of non-permissive cells (including most natural HIV-1 targets) by counteracting the cellular cytosine deaminases APOBEC-3G (hA3G) and hA3F. The Vif-induced degradation of these restriction factors by the proteasome has been extensively studied, but l...
