Xenopus kinesin catastrophe modulator-1 (XKCM1) is a Kin I kinesin family member that uses the energy of ATP hydrolysis to depolymerize microtubules. We demonstrated previously that XKCM1 is essential for mitotic-spindle assembly in vitro and acts by regulating microtubule dynamics as a pure protein, in extracts and in cells. A portion of the XKCM1 pool is(More)
In response to DNA damage, p53 undergoes post-translational modifications (including acetylation) that are critical for its transcriptional activity. However, the mechanism by which p53 acetylation is regulated is still unclear. Here, we describe an essential role for HLA-B-associated transcript 3 (Bat3)/Scythe in controlling the acetylation of p53 required(More)
Members of the California serogroup of bunyaviruses (family Bunyaviridae) are the leading cause of pediatric viral encephalitis in North America. Significant cell death is observed as part of the infection pathology. We now report that a Bunyaviral nonstructural protein termed NSs shows sequence similarity to Reaper, a proapoptotic protein from Drosophila.(More)
Apoptosis ensures tissue homeostasis in response to developmental cues or cellular damage. Recently reported genome-wide RNAi screens have suggested that several metabolic regulators can modulate caspase activation in Drosophila. Here, we establish a previously unrecognized link between metabolism and Drosophila apoptosis by showing that cellular NADPH(More)
