Anti-CTCF Rabbit Polyclonal Antibody

Catalog Number: (10107-362)
Supplier: Prosci
Description: CTCF is a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains. This nuclear protein is able to use different combinations of the ZF domains to bind different DNA target sequences and proteins. Depending upon the context of the site, the protein can bind a histone acetyltransferase (HAT)-containing complex and function as a transcriptional activator or bind a histone deacetylase (HDAC)-containing complex and function as a transcriptional repressor. If the protein is bound to a transcriptional insulator element, it can block communication between enhancers and upstream promoters, thereby regulating imprinted expression. Mutations in CTCF have been associated with invasive breast cancers, prostate cancers, and Wilms' tumors.This gene is a member of the BORIS + CTCF gene family and encodes a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains.

Anti-ATF2 Rabbit Polyclonal Antibody (Cy5.5®)

Catalog Number: (10484-930)
Supplier: Bioss
Description: This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds to the cAMP-responsive element (CRE), an octameric palindrome. It forms a homodimer or a heterodimer with c-Jun and stimulates CRE-dependent transcription. This protein is also a histone acetyltransferase (HAT) that specifically acetylates histones H2B and H4 in vitro; thus it may represent a class of sequence-specific factors that activate transcription by direct effects on chromatin components. Several alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012].

Anti-HDAC2 Mouse Monoclonal Antibody [clone: HDAC2-62]

Catalog Number: (89359-226)
Supplier: Genetex
Description: The basic repeating unit of chromatin is the nucleosome, which is composed of a protein octamer containing two each of the core histones H2A, H2B, H3, and H4, surrounded by approximately 146 base pairs of DNA. Reversible acetylation of highly conserved lysine residues in the N-terminal tail domains of core histones plays an important role in transcriptional regulation, cell cycle progression, and development events. Several histone acetyltransferases (HATs) catalyze this acetylation reaction (e.g. GCN5, PCAF, p300/CBP, TAFII250, P/CAF, SRC-1, BRCA-2). Acetylation of the core histones is generally considered to be associated with gene activation, probably through maintenance of the unfolded structure of transcribing nucleosomes. Histone acetylation is a dynamic process in which levels are determined by the net activities of HATs and the competing enzymes histone deacetylases (HDACs). Both activities are associated with the nuclear matrix. Eleven different mammalian HDACs have been described. HDACs 1-3 & 8 (Class I) are similar to yeast Rpd3 protein, while HDACs 4-7, 9 & 10 (Class II) are similar to yeast Hda1 protein. The activities of the histone deacetylases are often, but not always, associated with transcriptional repression and nucleosome condensation. HDAC1, HDAC2 and several others are the catalytic subunits of different multiprotein regulatory complexes. Other components of such complexes may include: corepressors such as mSin3, N-CoR, SMRT, associated proteins such as SAP18, SAP30, RbAp46, RbAp48, and c-Ski oncogenic protein (involved in DNA methylation). Nucleosome remodeling and deacetylation (NRD) complexes containing HDAC1, HDAC2, Mi-2 (CH3, CH4) dermatomyositis specific autoantigen, and MAT2 (metastasis-associated protein) (related to MAT1) have been described. It is therefore assumed that ATP-dependent nucleosome remodeling activity and histone deacetylation may be interconnected or interdependent. Recruitment of the multiprotein complexes to promoter sites occurs by many sequence specific DNA-binding proteins such as unliganded nuclear hormone receptors, DP1-E2F, YY1, and Rb family of transcription factors, transcriptional repressors, and tumor suppressors (e.g. BRCA1). Aberrant recruitment of HDACs by various oncoproteins may occur in certain neoplastic diseases. It has been found that inhibition ofHDAC2 activity by valporic acid induces proteosomal degradation of HDAC2.

Anti-CHD1 Rabbit Polyclonal Antibody

Catalog Number: (10084-434)
Supplier: Proteintech
Description: CHD1 belongs to the SNF2/RAD54 helicase family. CHD1 is an aTP-dependent chromatin-remodeling factor which functions as substrate recognition component of the transcription regulatory histone acetylation (HAT) complex SAGA. CHD1 regulates polymerase II transcription. It is required for efficient transcription by RNA polymerase I, and more specifically the polymerase I transcription termination step. CHD1 regulates negatively DNA replication. It is required to maintain a specific chromatin configuration across the genome. It is associated with histone deacetylase (HDAC) activity. CHD1 is required for the bridging of SNF2, the FACT complex, the PAF complex as well as the U2 snRNP complex to H3K4me3. It functions to modulate the efficiency of pre-mRNA splicing in part through physical bridging of spliceosomal components to H3K4me3. It is required for maintaining open chromatin and pluripotency in embryonic stem cells. The antibody is specific to CHD1.

Anti-HDAC3 Rabbit Polyclonal Antibody

Catalog Number: (10088-128)
Supplier: Proteintech
Description: Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA. Histone deacetylase (HDAC) and histone acetyltransferase (HAT) are enzymes that regulate transcription by selectively deacetylating or acetylating the (-amino groups of lysines located near the amino termini of core histone proteins. At least 4 classes of HDAC were identified. HDAC3 is a class I HDAC. HDAC3 has histone deacetylase activity and may participate in the regulation of transcription through its binding with the zinc-finger transcription factor YY1. HDAC3 can also down-regulate p53 function and thus modulate cell growth and apoptosis. The gene encoding HDAC3 is regarded as a potential tumor suppressor gene. This antibody is a rabbit polyclonal antibody raised against an internal region of human HDAC3.

Anti-H3 Mouse Monoclonal Antibody [clone: AH3-120]

Catalog Number: (89359-236)
Supplier: Genetex
Description: Histone proteins H3, H4, H2A, and H2B function as building blocks to package eukaryotic DNA into repeating nucleosome units that are folded in higher order chromatin fibers. The nucleosome is composed of an octamer containing a H3/H4 tetramer and two H2A/H2B dimers, surrounded by approximately 146 base pairs of DNA. A diverse and elaborate array of post-translational modifications including acetylation, phosphorylation, methylation, ubiquitination, and ADP-ribosylation occurs on the N-terminal tail domains of histones. Acetylation of lysine residues within these N-terminal domains by histone acetyl-transferases (HATs), including Gcn5p, P/CAF, p300/CBP, and TAFII250, is associated with transcriptional activation. This modification results in remodeling of the nucleosome structure into an open conformation more accessible to transcription complexes. Conversely, histone deacetylation by histone deacetylases (HDACs) is associated with transcription repression reversing the chromatin remodeling process. In most species, histone H3 is primarily acetylated at lysine 9, 14, 18, and 23. Acetylation at lysine 9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms.

Anti-MYST1/KAT8 Rabbit Polyclonal Antibody

Catalog Number: (77436-940)
Supplier: Bioss
Description: Dosage compensation ensures that males with a single X chromosome and females with two X chromosomes have the same amount of most X-linked gene products. In Drosophila, this is acheived by enhancing the level of transcription of the X chromosome in males. Proteins such as maleless, male specific lethal 1, 2 and 3, and males absent on the first (MOF) form a dosage compensation complex (DCC) that is required for the twofold increase of transcription of the male X chromosome. The DCC is preferentially associated with many sites on the X chromosome in somatic cells of males. The binding of the DCC to the X chromosome is dependent upon histone 4 acetylation at lysine 16, which is accomplished by MOF. In mammals, MOF (also designated hMOF, MYST1, or MOZ) belongs to the MYST family of histone acetyl transferases which are characterized by a unique C2HC-type zinc finger close to their HAT domains. MOF utilizes the zinc finger domain to contact the globular part of the nucleosome as well as the histone H4 N-terminal tail substrate. The carboxy terminal domain of human MOF also has histone acetyltransferase activity directed against histones H3 and H2A, a characteristic shared with other MYST family histone acetyltransferases.
