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.
Forms transcriptional repressor complexes by associating with MAD, SIN3, YY1 and N-COR. Interacts in the late S-phase of DNA-replication with DNMT1 in the other transcriptional repressor complex composed of DNMT1, DMAP1, PCNA, CAF1. Deacetylates TSHZ3 and regulates its transcriptional repressor activity.
组织特异性Widely expressed; lower levels in brain and lung.
序列相似性Belongs to the histone deacetylase family. HD type 1 subfamily.
翻译后修饰S-nitrosylated by GAPDH. In neurons, S-Nitrosylation at Cys-262 and Cys-274 does not affect the enzyme activity but abolishes chromatin-binding, leading to increases acetylation of histones and activate genes that are associated with neuronal development. In embryonic cortical neurons, S-Nitrosylation regulates dendritic growth and branching.

Chromatin was isolated and pooled from the two PF cortices of a single mouse. ChIP experiments were performed using a minimum of 3 mice per group. Chromatin was sheared in an ice bath by a 25 cycles of 30 sec on/off sonication using the “Bioruptor UCD-20” sonicator. Samples were kept on ice during 30 s between two pulses. An aliquot of precleared chromatin was collected as the input. The samples were incubated overnight at 4°C with 5 µl ab12169. The immunoprecipitated chromatin was analyzed by quantitative PCR with primers designed to amplify short regions of the promoters of genes of interest.
ChIP assay on c-Fos gene promoter using ab12169 antibody. Results show a significant lower enrichment of HDAC 2 in PF cortex of (amyloid precursor protein) APP−/− mouse, Student’s t-test: **p<0.01. IgG was used as negative control. Equal amounts of ChIP and input chromatin were used for qRT-PCR analysis on the c-Fos gene promoter. Enrichment values were normalized to input values and represented the average of three or more mice per experiment. Results are expressed as mean ± SD.
ab12169 staining HDAC2 in a human glioblastoma cell line by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with Triton X-100 (0.1%) in PBS and blocked with 0.5% BSA for 20 minutes at room temperature. Samples were incubated with primary antibody (1/50 in PBS + 0.5% BSA) for 16 hours at 4°C. An Alexa Fluor®488-conjugated Goat anti-mouse monoclonal (1/400) was used as the secondary antibody. Nuclei were counterstained with Hoechst (blue).
