XMAP215 belongs to a family of proteins involved in the regulation of microtubule dynamics. In this study we analyze the function of different parts of XMAP215 in vivo and in Xenopus egg extracts. XMAP215 has been divided into three fragments, FrN, FrM and FrC (for N-terminal, middle and C-terminal, respectively). FrN co-localizes with microtubules in egg(More)
Recently we have found that the drug amiodarone induces apoptosis in yeast, which is mediated by reactive oxygen species (ROS). Here we have used this finding as a tool to screen for genes involved in the death program. We have described a novel mitochondrial protein, Ysp2, acting in the amiodarone-induced death cascade. After amiodarone addition both the(More)
Huntington's disease is caused by specific mutations in huntingtin protein. Expansion of a polyglutamine (polyQ) repeat of huntingtin leads to protein aggregation in neurons followed by cell death with apoptotic markers. The connection between the aggregation and the degeneration of neurons is poorly understood. Here, we show that the physiological(More)
