Research Abstract

To examine the chromatin structure in centromere region, we tried to identify proteins that associate with the CENP-T/CENP-W complex based on high sensitive Mass Spectrometry combined with the immunoprecipitation. We identified a protein Eaf6 and we confirmed that this localized to the centromeres. We also identified a histone acethyltransferase as an Eaf6-interacting protein. To examine function of Eaf6, we established an Eaf6-conditional knockout cell line and found that localization of several centromere proteins were abolished in Eaf6-deficient cells based on SILAC analysis, indicating that the Eaf6 complex might be required for chromatin architecture of centromeres through the acethyltransferase activity of the Eaf6 complex.
