Anti-RPAIN antibody produced in rabbit

产品说明

一般描述

RPAIN (replication protein A interacting protein), also known as RIP (RPA interacting protein), is an adaptor protein, that is transcribed into 9 isoforms as obtained from a premade human fetal brain library. The longest isoform is hRIPa, which is composed of 219 amino acids. It contains an arginine-rich basic region in its N-terminal, succeeded by an acidic region and two Zn finger-like domains in its C-terminal. hRIPβ lacks one Zn finger-like region. RPAIN gene is localized to human chromosome 17p13 and is composed of seven exons.

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

RPAIN (replication protein A interacting protein) functions as a linker between RPA (replication protein A) protein and importin β. This complex between the a isoform of RPAIN and importin β facilitates the transport of RPA into the nucleus. In cervical cancer cells, the a form is elevated, where it controls cell proliferation through the regulation of RPA transport. RPAINβ resides in the promyelocytic leukemia (PML) nuclear bodies, where it is responsible for the transportation of RPA into the PML bodies. It is also responsible for the release of RPA upon UV (ultraviolet) irradiation. This protein promotes the IRES (internal ribosome entry site)-mediated translation of HIV-1 (human immunodeficiency virus).

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.
