Description:
Aurora B is a component of the chromosomal passenger complex (CPC) required for correct spindle-kinetochore attachments during chromosome segregation and for cytokinesis. The chromatin factors that recruit the CPC to centromeres are unknown, however. Here we show that phosphorylation of histone H3 threonine 3 (H3T3ph) by Haspin is necessary for CPC accumulation at centromeres and that the CPC subunit Survivin binds directly to H3T3ph. A nonbinding Survivin-D70A/D71A mutant does not support centromeric CPC concentration, and both Haspin depletion and Survivin-D70A/D71A mutation diminish centromere localization of the kinesin MCAK and the mitotic checkpoint response to taxol. Survivin-D70A/D71A mutation and microinjection of H3T3ph-specific antibody both compromise centromeric Aurora B functions but do not prevent cytokinesis. Therefore, H3T3ph generated by Haspin positions the CPC at centromeres to regulate selected targets of Aurora B during mitosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2967368/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2967368/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Fangwei -- Dai, Jun -- Daum, John R -- Niedzialkowska, Ewa -- Banerjee, Budhaditya -- Stukenberg, P Todd -- Gorbsky, Gary J -- Higgins, Jonathan M G -- R01 GM050412/GM/NIGMS NIH HHS/ -- R01 GM050412-16/GM/NIGMS NIH HHS/ -- R01 GM063045/GM/NIGMS NIH HHS/ -- R01 GM063045-10/GM/NIGMS NIH HHS/ -- R01 GM074210/GM/NIGMS NIH HHS/ -- R01 GM074210-04/GM/NIGMS NIH HHS/ -- R01-GM050412/GM/NIGMS NIH HHS/ -- R01-GM063045/GM/NIGMS NIH HHS/ -- R01-GM074210/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):231-5. doi: 10.1126/science.1189435.
