How sister kinetochores attach to microtubules from opposite spindle poles during mitosis (bi-orientation) remains poorly understood. In yeast, the ortholog of the Aurora B-INCENP protein kinase… (More)
Tagging of genes by chromosomal integration of PCR amplified cassettes is a widely used and fast method to label proteins in vivo in the yeast Saccharomyces cerevisiae. This strategy directs the… (More)
Half a century of biochemical and biophysical experiments has provided attractive models that may explain the diverse functions of microtubules within cells and organisms. However, the notion of… (More)
The microtubule cytoskeleton is crucial for the internal organization of eukaryotic cells. Several microtubule-associated proteins link microtubules to subcellular structures. A subclass of these… (More)
Here, we show that the budding yeast proteins Ndc80p, Nuf2p, Spc24p and Spc25p interact at the kinetochore. Consistently, Ndc80p, Nuf2p, Spc24p and Spc25p associate with centromere DNA in chromatin… (More)
We show here that Ask1p, Dad2p, Spc19p and Spc34p are subunits of the budding yeast Duo1p-Dam1p- Dad1p complex, which associate with kinetochores and localize along metaphase and anaphase spindles.… (More)
Microtubules are cytoskeletal filaments that are dynamically assembled from α/β-tubulin heterodimers. The primary sequence and structure of the tubulin proteins and, consequently, the properties and… (More)
In the past decades, a range of post-translational modifications has been discovered on tubulins, the major constituents of microtubules. Pioneering studies have described the occurrence and dynamics… (More)
Polyglutamylation is a posttranslational modification that generates glutamate side chains on tubulins and other proteins. Although this modification has been shown to be reversible, little is known… (More)
Posttranslational glutamylation of tubulin is present on selected subsets of microtubules in cells. Although the modification is expected to contribute to the spatial and temporal organization of the… (More)
