Abstract excerpt
A temperature-sensitive growth mutant tsFS20 isolated from mouse FM3A cells was identified as a mutant with thermolabile ubiquitin-activating enzyme E1 by transfection with a full-length cDNA encoding the human E1 enzyme and cell-cell hybridization with an authentic E1 mutant ts85 previously isolated from FM3A cells. The resulting transformants produced thermoresistant E1 activity. Upon shift-up of temperature,...
