Targeting Protein Stability with a Small Molecule

Targeting Protein Stability with a Small Molecule

Both genetic approaches and small-molecule inhibitors can be used to perturb protein function. Banaszynski et al. (2006) now describe a strategy to regulate the stability of a target protein, in which specificity is provided by a genetically encoded tag and temporal control is imparted by a small molecule.

Small Molecule Inhibitors Targeting Activator Protein 1 (AP-1)

Activator protein 1 (AP-1) is a pivotal transcription factor that regulates a wide range of cellular processes including proliferation, apoptosis, differentiation, survival, cell migration, and transformation. Accumulating evidence supports that AP-1 plays an important role in several severe disorders including cancer, fibrosis, and organ injury, as well as inflammatory disorders such as asthma...

A Novel Small-molecule Inhibitor Targeting

Profiling protein function with small molecule microarrays.

The regulation of protein function through posttranslational modification, local environment, and protein-protein interaction is critical to cellular function. The ability to analyze on a genome-wide scale protein functional activity rather than changes in protein abundance or structure would provide important new insights into complex biological processes. Herein, we report the application of ...

Small molecule toxins targeting tumor receptors.

Targeting toxic therapeutics to tumors through receptors over expressed on the surface of cancer cells can reduce systemic toxicity and increase the effectiveness of the targeted compounds. Small molecule targeted therapeutics have a number of advantages over toxic immunoconjugates including better tumor penetration, lack of neutralizing host immune response and superior flexibility in selectio...
