The SIT4 protein phosphatase functions in late G1 for progression into S phase.

Molecular and cellular biology - 1 Apr 1991

Sutton A, Immanuel D, Arndt K T

Abstract excerpt

Saccharomyces cerevisiae strains containing temperature-sensitive mutations in the SIT4 protein phosphatase arrest in late G1 at the nonpermissive temperature. Order-of-function analysis shows that SIT4 is required in late G1 for progression into S phase. While the levels of SIT4 do not change in the cell cycle, SIT4 associates with two high-molecular-weight phosphoproteins in a cell-cycle-dependent fashion. In...
