The peptidyl prolil cis/trans isomerase Ess1/Pin1 is essential for mitosis
progression in yeast cells and is hypothesized to perform the same role in
mammalian cells. To investigate the function of Pin1 in mammalian cells, we
created mice lacking Pin1. These mice underwent normal development. Althou
gh the embryonic Pin1-/- fibroblasts grew normally, they proved significant
ly deficient in their ability to restart proliferation in response to serum
stimulation after G(0) arrest. These results suggest that Pin1 is required
for cell cycle progression from G(0) arrest as well as mitosis progression
in normal mammalian cells. (C) 1999 Academic Press.
