Synonyms: Anti-RING finger protein 43 precursor
Storage: -20C
Application: 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.

Biochem Physiol Actions: RNF43 (ring finger protein 43) gene encodes a RING-type E3 ubiquitin ligase that functions as a negative regulator of the Wnt signaling pathway. It is involved in the ubiquitination, endocytosis and targeting of Wnt receptor complex components Frizzled receptors to lysosomes. It is localized to the endoplasmic reticulum (ER) and also present in the nuclear envelope. It interacts with HAP95, a chromatin-associated protein, and may regulate cell growth. RNF43 has been implicated in the pathogenesis of colon cancer. It also functions as a tumor suppressor in the intestinal stem cell zone.
