Anti-RNF26 antibodies are used in the immunodetection of the protein ring finger protein 26. In humans, the canonical protein has a reported length of 433 amino acid residues and a mass of 47.7 kDa. Its subcellular localization is in the ER. It is ubiquitously expressed across many tissue types. Among its functions, RNF26 is involved with protein ubiquitination. Synonyms for this target antigen include E3 ubiquitin-protein ligase RNF26 and ring finger protein with leucine zipper.
