abstract = {The mitotic exit network (MEN) is a conserved signalling
pathway essential for the termination of mitosis in the
budding yeast Saccharomyces cerevisiae. All MEN components
are highly conserved in the methylotrophic budding yeast
Ogataea polymorpha, except for Cdc15 kinase. Instead, we
identified two essential kinases OpHcd1 and OpHcd2
(homologue candidate of ScCdc15) that are homologous to
SpSid1 and SpCdc7, respectively, components of the septation
initiation network (SIN) of the fission yeast
Schizosaccharomyces pombe. Conditional mutants for OpHCD1
and OpHCD2 exhibited significant delay in late anaphase and
defective cell separation, suggesting that both genes have
roles in mitotic exit and cytokinesis. Unlike Cdc15 in S.
cerevisiae, the association of OpHcd1 and OpHcd2 with the
yeast centrosomes (named spindle pole bodies, SPBs) is
restricted to the SPB in the mother cell body. SPB
localisation of OpHcd2 is regulated by the status of OpTem1
GTPase, while OpHcd1 requires the polo-like kinase OpCdc5 as
well as active Tem1 to ensure the coordination of mitotic
exit (ME) signalling and cell cycle progression. Our study
suggests that the divergence of molecular mechanisms to
control the ME-signalling pathway as well as the loss of
Sid1/Hcd1 kinase in the MEN occurred relatively recently
during the evolution of budding yeast.},
