TRIM56 encodes the human gene, Tripartite motif containing 56. It may also be known as: E3 ubiquitin-protein ligase TRIM56; Tripartite motif-containing protein 56; E3 ubiquitin-protein ligase TRIM56 ; RING finger protein 109; RNF109. The encoded protein is an enzyme with an amino acid length of 755 and a mass of 81.5 kDa. Other isoforms may exist. TRIM56 is a member of the TRIM/RBCC family. Homologs of this gene exist in other organisms, including: Mouse.
