Structural insights into electron transfer in caa3-type cytochrome oxidase.

abstract：:Interferon-induced proteins with tetratricopeptide repeats (IFITs) are innate immune effector molecules that are thought to confer antiviral defence through disruption of protein-protein interactions in the host translation-initiation machinery. However, it was recently discovered that IFITs can directly recognize vir...

abstract：:Mov13 mice carry a single Moloney murine leukaemia virus (M-MuLV) proviral copy in the first intron of the alpha 1(I) collagen gene. Virus insertion interferes with the synthesis of stable alpha 1(I) collagen messenger RNA and causes a recessive lethal mutation. The virus insertion has induced changes of the methylati...
