With use and time things wear out. Tires get worn on a car, and you have the old tires removed, recycled, and replaced with new ones. Sometimes a part or piece of something isn’t made properly. For instance, if you are assembling a piece of furniture and you find a screw with no threads, you […]
This post was written by guest blogger Iain Ronald, Director Academic/Government Market Segment at Promega.My back story is similar to most of you reading this blog, high school education, undergraduate degree then onto a postgraduate degree. However, over 25 years ago during my undergraduate study, I was fortunate enough to work in the lab of […]
Recently, selectively targeting proteins for degradation using the cell’s natural ubiquitin proteasome pathway (UPS) has surfaced as an effective strategy to bypass difficult-to-drug proteins related to diseases like cancer. Using sensitive bioluminescence technology, CRISPR-edited cell lines can facilitate studying popular protein degradation targets. NanoLuc® Luciferase (NLuc) has made biology more accessible than ever (1). Further […]
The Dana-Farber Targeted Protein Degradation Webinar Series discusses new discoveries and modalities in protein degradation. In this webinar, Senior Research Scientist, Dr. Danette Daniels, focuses primarily on proteolysis-targeting chimeras, or PROTACs. A variety of topics are covered including the design, potency, and efficacy of PROTACs in targeted protein degradation. Watch the video below to learn […]
Transcriptional activation of genes within the nucleus of eukaryotic cells occurs by a variety of mechanisms. Typically, these mechanisms rely on the interaction of regulatory proteins (transcriptional activators or repressors) with specific DNA sequences that control gene expression. Upon DNA binding, regulatory proteins also interact with other proteins that are part of the RNA polymerase […]
Our cells have evolved multiple mechanisms for “taking out the trash”—breaking down and disposing of cellular components that are defective, damaged or no longer required. Within a cell, these processes are balanced by the synthesis of new components, so that DNA, RNA and proteins are constantly undergoing turnover. Proteins are degraded by two major components […]
PROTACs or Proteolysis-Targeting Chimeras are an emerging tool in protein degradation studies, potentially suited to any need involving the removal of a specific protein. These small-molecule chimeras are exciting due to: 1) their target specificity; and 2) their ability to enable target destruction versus target inhibition. Here we discuss a paper that presents a roadmap […]
