Anti-AO7 antibodies enable researchers to detect and measure the AO7 antigen in biological samples. This target is a reported synonym of the RNF25 gene, which encodes ring finger protein 25. This protein is known to function in NF-kappaB signaling pathways and protein ubiquitination, among other biological roles. The human version of AO7 has a canonical amino acid length of 459 residues and a protein mass of 51.2 kilodaltons.
