Anti-PRPF4 antibody produced in rabbit

产品说明

一般描述

PRPF4 (Pre-mRNA processing factor 4) encodes a 60kDa protein (hPrp4) consisting of 522 amino acids with seven WD40 repeats at its C-terminal end. It is a member of the Ser/Thr protein kinase family and is mapped on chromosome 9q32. It is widely expressed in human tissues and in murine neuronal cells (neural retina and retinal pigmented epithelium cells).

免疫原

U4/U6 small nuclear ribonucleoprotein Prp4 recombinant protein epitope signature tag (PrEST)

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

PRPF4 (Pre-mRNA processing factor 4) is a spliceosomal protein highly involved in the pre-mRNA splicing. It acts as a component of U4/U5/U6 tri-snRNP complex during the formation of active core of the spliceosome. Mutation in PRPF4 causes an autosomal dominant disorder, retinitis pigmentosa (RP) characterized with progressive loss of photoreceptors. PRPF4 also plays a role in cell mitosis by participating in the regulation of mitotic spindle assembly.

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.
