Title | Pds5 Regulates Sister-Chromatid Cohesion and Chromosome Bi-orientation through a Conserved Protein Interaction Module. |
Journal | Curr Biol |
Abstract |
Sister-chromatid cohesion is established by the cohesin complex in S phase and persists until metaphase, when sister chromatids are captured by microtubules emanating from opposite poles [1]. The Aurora-B-containing chromosome passenger complex (CPC) plays a crucial role in achieving chromosome bi-orientation by correcting erroneous microtubule attachment [2]. The centromeric localization of the CPC relies largely on histone H3-T3 phosphorylation (H3-pT3), which is mediated by the mitotic histone kinase Haspin/Hrk1 [3-5]. Hrk1 localization to centromeres depends largely on the cohesin subunit Pds5 in fission yeast [5]; however, it is unknown how Pds5 regulates Hrk1 localization. Here we identify a conserved Hrk1-interacting motif (HIM) in Pds5 and a Pds5-interacting motif (PIM) in Hrk1 in fission yeast. Mutations in either motif result in the displacement of Hrk1 from centromeres. We also show that the mechanism of Pds5-dependent Hrk1 recruitment is conserved in human cells. Notably, the PIM in Haspin/Hrk1 is reminiscent of the YSR motif found in the mammalian cohesin destabilizer Wapl and stabilizer Sororin, both of which bind PDS5 [6-12]. Similarly, and through the same motifs, fission yeast Pds5 binds to Wpl1/Wapl and acetyltransferase Eso1/Eco1, in addition to Hrk1. Thus, we have identified a protein-protein interaction module in Pds5 that serves as a chromatin platform for regulating sister-chromatid cohesion and chromosome bi-orientation. |
