The protein encoded by this gene is a member of the tripartite motif (TRIM) family, also called the 'RING-B-box-coiled-coil' (RBCC) subgroup of RING finger proteins. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. This protein localizes to cytoplasmic filaments. It is similar to a rat protein which is a specific partner for the tail domain of myosin V, a class of myosins which are involved in the targeted transport of organelles. The rat protein can also interact with alpha-actinin-4. Thus it is suggested that this human protein may play a role in myosin V-mediated cargo transport. Alternatively spliced transcript variants encoding the same isoform have been identified.[6]

Interactions

TRIM3 has been shown to interact with Actinin alpha 4.[7]

TRIM3 binds to and ubiquitinates Estrogen receptor alpha (ERa) leading to receptor's stabilization.[8]

Moreover, TRIM3 interacts with P53 which promotes the formation of K48-linked poly-ubiquitin chains and degradation.[9]
