Nuclear preservation and cytoplasmic degradation of human immunodeficiency virus type 1 Rev protein.

Abstract excerpt

Rev, a major regulatory protein of human immunodeficiency virus type 1, has been demonstrated to shuttle between the nucleus and cytoplasm of infected cells. The fate of the Rev protein in living cells was evaluated by pulse-chase experiments using a transient Rev expression system. Sixteen hours after chasing with unlabelled amino acids, 45% of the labelled Rev was still present, which clearly indicates a long...
