Previous experiments suggest a connection between the N-alpha-acetylation of proteins and sensitivity of cells to apoptotic signals. Here, we describe a biochemical assay to detect the acetylation status of proteins and demonstrate that protein N-alpha-acetylation is regulated by the availability of acetyl-CoA. Because the antiapoptotic protein Bcl-xL is(More)
An image-based phenotypic screen was developed to identify small molecule regulators of intracellular traffic. Using this screen we found that AG1478, a previous known inhibitor of epidermal growth factor receptor (EGFR), had an EGFR independent activity in inducing the disassembly of the Golgi in human cells. Similar to Brefeldin A (BFA), a known disrupter(More)
