WebJan 3, 2014 · Wilkins et al. (p. 77) used ultraviolet cross-linker amino acids in the histones of bakers' yeast to show that during early mitosis, phosphorylation of H3 threonine 3 by Haspin kinase recruits the chromosome passenger complex (CPC). The subsequent phosphorylation of H3 serine 10 by CPC allows the recruitment of the deacetylase Hst2p … Cdc42 activation in budding yeast mainly relies on the essential GEF Cdc245,6,7,8,9,10: precise localization of Cdc24 is crucial to locally activate Cdc42. The accumulation of polarized Cdc42-GTP at the bud tip might be explained by a persistent polarization of the GEF. We thus analyzed Cdc24 … See more A physical interaction between Cdc24 and active Ras has been previously described in S. pombe and C. neoformans, although its functional significance was not … See more To clarify how haspin impacts on active Ras and hence modulates Cdc24 distribution, we investigated whether haspin affected the localization of Ras-GTP.
