A new study reveals that DELLA proteins directly interact with the prefoldin complex, thus regulating tubulin subunit availability in a gibberellin-dependent manner. This finding provides a mechanistic link between the growth-promoting plant hormone gibberellin and cortical microtubule organization.

The longevity associated protein p66Shc has been suggested to regulate organismal lifespan through initiation of apoptotic pathways. Following stress-induced translocation into the mitochondria, p66Shc promotes increased reactive oxygen species (ROS) production and triggers poorly defined downstream signaling events that lead to decreased cell viability. Protein disulfide bonding has recently emerged as aROSdependent post-translational modification that regulates protein function and signaling processes. Using the mouse hippocampal HT-22 cell line, I sought to determine the changes in the disulfide proteome associated with p66Shc mediatedROSproduction. Through Redox 2D-SDSPAGEanalysis of mitochondrial and cytosolic extracts, redox sensitive proteins altered by p66Shc mediatedROSformation were identified. Of …
