Phenotypic characterization of mutants in vaccinia virus gene G2R, a putative transcription elongation factor.

abstract：:The HTLV-1 singly spliced open reading frame I protein, p12(I), is highly unstable and appears to be necessary for persistent infection in rabbits. Here we demonstrate that p12(I) forms dimers through two putative leucine zipper domains and that its stability is augmented by specific proteasome inhibitors. p12(I) is u...
