Anti-RNF209 antibodies enable researchers to detect and measure the RNF209 antigen in biological samples. This target is a reported synonym of the TRIML1 gene, which encodes tripartite motif family like 1. This protein is known to function in innate immune responses and protein ubiquitination, among other biological roles. The human version of RNF209 has a canonical amino acid length of 468 residues and a protein mass of 53 kilodaltons.
