Anti-RFFL antibody produced in rabbit

HPA019492    Human Protein Atlas characterization data

RFFL (Ring finger and FYVE-like domain containing E3 ubiquitin protein ligase) is a caspase-associated ring protein belonging to a family of protein ubiquitin ligases. It consists of a specialized FYVE-type zinc finger domain, a cramped phosphoinositide binding pocket and a blunted membrane insertion loop.

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. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

RFFL (Ring finger and FYVE-like domain containing E3 ubiquitin protein ligase) is highly involved in the p53 signaling pathway. It directly interacts with the critical regulator of p53 turnover, MDM2 and it stabilizes MDM2 by inhibiting its ubiquitination. Its distinct FYVE domains also possess binding affinity to phosphatidylinositol 3-phosphate in lipid bilayers.

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.

Corresponding Antigen APREST74251.
