General description

Histone acetyltransferases (HATs) have critical roles in cellular functions and are involved in the regulation of gene transcription, differentiation, and proliferation. The HAT Activity Colorimetric Assay Kit offers a convenient, non-radioactive system for a rapid and sensitive detection of HAT activity in mammalian samples. The kit includes an active Nuclear Extract (NE) to be used as a positive control, HAT cofactor, acetyl-CoA, and all downstream cofactors and substrates. Acetylation of a peptide substrate by active HAT releases the free form of CoA, which then serves as an essential coenzyme for producing NADH. NADH can easily be detected spectrophotometrically upon reacting with a soluble tetrazolium dye. The detection can be continuous, and therefore, is suitable for kinetic studies. The kit provides all reagents and a simple, straightforward protocol for a complete assay.

Features and Benefits

  • Sensitive and reliable assay
  • Utilizes colorimetric methods
  • Sample type: cell and tissue lysates
  • Species reactivity: mammalian
  • Suitable for individual tests or high throughput assays and kinetic studies
  • Easy and simple procedure: combine nuclear extract or protein sample with reagents, incubate, and read absorbance
  • Convenient 96-well microplate format
  • Continuously measures HAT activity; suitable for kinetic studies
  • No HDAC interference; crude nuclear extract can be used directly

Ribosome biogenesis drives cell growth and proliferation, but mechanisms that modulate this process within specific lineages remain poorly understood. Here, we identify a Drosophila RNA polymerase I (Pol I) regulatory complex composed of Under-developed (Udd), TAF1B, and a TAF1C-like factor.

We report that H3K9 HMTase G9a activates transcription of the cell cycle regulatory gene, p21, in p53-null H1299 cells. Positive regulation of p21 by G9a is independent of its HMTase activity. We demonstrate that G9a upregulates p21 via interaction with
