Application

MB-3 has been used as a general control non-repressible 5 (GCN5) inhibitor:
  • to study its effects on lamin A/C-associated pY19-Cav-2-mediated histone H3 acetylations
  • to analyze its effects on the growth of Arabidopsis thaliana seedlings
  • to study its effects on craniofacial chondrocyte maturation

Biochem/physiol Actions

MB-3 can modify the gene expression in murine embryonic stem cells as well as yeast. It hinders the acetyltransferase activity of general control non-repressible 5 (GCN5) by binding to acetyl CoA pocket present in GCN5.
MB-3 is a Gcn5 HAT (Histone Acetyltransferase) inhibitor; anti-inflammatory, anti-carcinogenic.

The connection between diabetes and Alzheimer's disease (AD) is not fully determined. Hyperphosphorylation of tau protein is mediated by binding and stabilization of truncated p25 with cyclin-dependent kinase-5 (CDK5) in AD. We recently showed that diabetes-associated hyperglycemia increased the CDK5

Cell fate transitions in mammalian stem cell systems have often been associated with transcriptional heterogeneity; however, existing data have failed to establish a functional or mechanistic link between the two phenomena. Experiments in unicellular organisms support the notion that transcriptional

Mesenchymal stem cells (MSCs) specifically differentiate into cardiomyocytes as a potential way to reverse myocardial injury diseases, and uncovering this differentiation mechanism is immensely important. We have previously shown that histone acetylation/methylation and DNA methylation are involved in MSC differentiation

Post-translational modifications of histone variant H2A.Z accompany gene transactivation, but its modifying enzymes still remain elusive. Here, we reveal a hitherto unknown function of human KAT2A (GCN5) as a histone acetyltransferase (HAT) of H2A.Z at the promoters of a set

Candida species represent one of the most frequent causes of hospital-acquired infections in immunocompromised patient cohorts. Due to a very limited set of antifungals available and an increasing prevalence of drug resistance, the discovery of novel antifungal targets is essential.
