产品概述
Inhibition of histone deacetylase (HDAC) has been implicated in the modulation of transcription and induction of apoptosis or differentiation in cancer cells.
However, screening of compounds for HDAC inhibition has been difficult due to the lack of convenient tools for analyzing HDAC activity.
The new Fluorometric HDAC Activity Assay Kit provides a fast and fluorescence-based method that eliminates radioactivity, extractions, or chromatography, as used in traditional assays.
The new procedure requires only two easy steps, both performed on the same microtiter plate.
First, the HDAC fluorometric substrate, which comprises an acetylated lysine side chain, is incubated with a sample containing HDAC activity (e.g., HeLa nuclear extract or others).
Deacetylation of the substrate sensitizes the substrate, so that, in the second step, treatment with the Lysine Developer produces a fluorophore.
The fluorophore can be easily analyzed using a fluorescence plate reader or a fluorometer.
The assay is well suited for high throughput screening applications.

说明
This product is manufactured by BioVision, an Abcam company and was previously called K330 HDAC Activity Fluorometric Assay Kit. K330-100 is the same size as the 96 test size of ab1438.
Read the entire protocol before beginning the procedure.
The HeLa extract should be refrozen immediately at –70°C after each use to avoid loss of activity.
If positive and negative controls are designed, the kit provides sufficient reagents for 5 positive control assays with the HeLa Nuclear Extract and 5 negative control assays with the HDAC Inhibitor, Trichostatin A.

功能
Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Deacetylates SP proteins, SP1 and SP3, and regulates their function. Component of the BRG1-RB1-HDAC1 complex, which negatively regulates the CREST-mediated transcription in resting neurons. Upon calcium stimulation, HDAC1 is released from the complex and CREBBP is recruited, which facilitates transcriptional activation. Deacetylates TSHZ3 and regulates its transcriptional repressor activity. Deacetylates 'Lys-310' in RELA and thereby inhibits the transcriptional activity of NF-kappa-B. Component a RCOR/GFI/KDM1A/HDAC complex that suppresses, via histone deacetylase (HDAC) recruitment, a number of genes implicated in multilineage blood cell development. -
组织特异性
Ubiquitous, with higher levels in heart, pancreas and testis, and lower levels in kidney and brain. -
序列相似性
Belongs to the histone deacetylase family. HD type 1 subfamily. -
翻译后修饰
Sumoylated on Lys-444 and Lys-476; which promotes enzymatic activity. Desumoylated by SENP1.
Phosphorylation on Ser-421 and Ser-423 promotes enzymatic activity and interactions with NuRD and SIN3 complexes. Phosphorylated by CDK5.
Ubiquitinated by CHFR, leading to its degradation by the proteasome (By similarity). Ubiquitinated by KCTD11, leading to proteasomal degradation. -
