Anti-PHF2 antibody produced in rabbit

产品说明

一般描述

PHF2 (PHD finger protein 2) is a member of α-ketoglutarate-Fe²⁺-dependent dioxygenases. This family of proteins contains three members namely, PHF2, PHF8 and KIAA1718. PHF2 gene maps to human chromosome 9q22. It contains a Jumonji domain and a plant homeodomain (PHD) at its N-terminal. Its C-terminal contains four repeats of TPAST sequence, along with a serine and threonine rich sequence. It has two possible PEST sequences and eight putative nuclear localization signals. It is widely expressed in most adult tissues.

应用

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

生化/生理作用

PHF2 (PHD finger protein 2) is a histone H3K9 demethylase that demethylates H3K9me1, and through its PHD (plant homeodomain) domain interacts with H3K4me3. Therefore, it regulates the demethylation of histone. However, it remains inactive unless phosphorylated by protein kinase A (PKA). Once activated, it forms a complex with a DNA-binding protein called ARID5B (AT rich interactive domain 5B). This causes demethylation of ARID5B, and PHF2- ARID5B complex then interacts with the target promoters. Hence, this complex regulates histone methylation and gene transcription. In mouse embryos, PHF2 is expressed in higher levels in neural tube and dorsal root ganglia, as opposed to its expression in other tissues. This expression profile suggests that PHF2 might have a role in hereditary sensory neuropathy type I (HSN1). This protein is found to be associated with many cancers, and its expression is up-regulated in esophageal squamous cell carcinoma (ESCC).

特点和优势

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
