Simulation:

Change of parameters: kicdh"=0, kscdh=0.03, MDT=150.
Length of G1 phase: 36.7 min.
Arrest: G2 arrest

Experiments:

Zachariae, W., Schwab, M., Nasmyth, K. and Seufert, W. (1998). Control of cyclin ubiquitination by CDK-regulated binding of Hct1 to the anaphase promoting complex. Science 282:1721-1724.
[Abstract] [Article]
Experimental results: Fig. 4, cells containing GALLp-HA3-Hct1-m11 failed to accumulate mitotic cyclin Clb2 and Clb3, and failed to form mitotic spindle or to undergo cytokinesis.

(Hct1-m11, where all eleven potential Cdk phosphorylation sites on Hct1 are removed, is constitutively active. GALL promoter is a weak galactose-inducible promoter.)
