Identification of multicopy suppressors of cell cycle arrest at the G1-S transition in Saccharomyces cerevisiae.

Abstract excerpt

Inactivation of HAL3 in the absence of SIT4 function leads to cell cycle arrest at the G(1)-S transition. To identify genes potentially involved in the control of this phase of the cell cycle, a screening for multicopy suppressors of a conditional sit4 hal3 mutant (strain JC002) has been developed. The screening yielded several genes known to perform key roles in cell cycle events, such as CLN3, BCK2 or SWI4,...
