This Week in Science

In a paper published online in advance in Science this week, investigators at Harvard Medical School and their colleagues show that the "phosphorylation of histone H3 threonine-3 (H3T3ph) by Haspin is necessary for chromosomal passenger complex accumulation at centromeres, and that the CPC subunit Survivin binds directly to H3T3ph." They also show that a non-binding Survivin-D70A/D71A mutant "does not support centromeric CPC concentration, and both Haspin depletion and Survivin-D70A/D71A mutation diminish centromere localization of MCAK and mitotic checkpoint signaling in taxol."
