Acceptor-photobleaching FRET analysis of core kinetochore and NAC proteins in living human cells.

Faithful chromatin segregation is mediated and controlled by the kinetochore protein network which assembles at centromeres. In this study, the neighbourhood relations of inner kinetochore and nucleosome-associated complex (NAC) proteins were analysed in living human interphase cells by acceptor photobleaching FRET. The data indicate that CENP-U is in close vicinity to CENP-I as well as to CENP-B and that CENP-M is close to CENP-T.
