TRIM21
52 kDa Ro protein é uma proteína que em humanos é codificada pelo gene TRIM21.
Auxilia anticorpos no interior das células a combater infecções, movendo os atacantes (ex. vírus) para o sistema de eliminação celular. Esse mecanismo foi catalogado na revista científica Proceedings of the National Academy of Sciences em 2010 e pode ser a chave para a criação de medicamentos antivirais mais efetivos, pois até então, era apenas conhecido que os anticorpos agiam por bloqueio somente fora das células.[1]
