Mitotic Histone H3 Phosphorylation by the NIMA Kinase in Aspergillus nidulans

  title={Mitotic Histone H3 Phosphorylation by the NIMA Kinase in Aspergillus nidulans},
  author={Colin P.C De Souza and Aysha H. Osmani and L. Wu and Jeffrey L Spotts and Stephen A Osmani},
Phosphorylation of histone H3 serine 10 correlates with chromosome condensation and is required for normal chromosome segregation in Tetrahymena. This phosphorylation is dependent upon activation of the NIMA kinase in Aspergillus nidulans. NIMA expression also induces Ser-10 phosphorylation inappropriately in S phase-arrested cells and in the absence of NIMX(cdc2) activity. At mitosis, NIMA becomes enriched on chromatin and subsequently localizes to the mitotic spindle and spindle pole bodies… CONTINUE READING
