Official Full Name: tripartite motif containing 5
Also known as: RNF88; TRIM5alpha
The protein encoded by this gene is a member of the TRIM family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coil region. The protein forms homo-oligomers through the coil-coil region and localizes to the cytoplasm. It appears to act as an E3 ubiquitin ligase and ubiquitinates itself to regulate its subcellular localization. It may play a role in restricting retroviruses. Multiple alternatively spliced transcript variants encoding different isoforms have been described for this gene.
