Background: Tripartite motif-containing protein 3 (TRIM3), also known as RING finger protein 22 (RNF22), RING finger protein 97 (RNF97) or brain-expressed RING finger protein (BERP), is a 744 amino acid member of the TRIM family, also known as the RING-B-box coiled-coil (RBCC) family. Members of the RBCC family have an N-terminal RING finger, followed by one or two zinc-binding domains (B-box domains), a leucine coiled-coil region and a variable C-terminal domain. Localized to cytoplasmic filaments, TRIM3 has been shown to interact with å-actinin-4 and myosin V, two proteins associated with the actin cytoskeleton. Specifically, å-actinin-4 interacts with the RBCC domain of TRIM3, and the C-terminal tail of Myosin V interacts with with the unique C-terminal ∫-propeller domain of TRIM3. These associations suggest that TRIM3 may play a role in cell motility and cargo transport. Three named isoforms of TRIM3 exist as a result of alternative splicing events.
