Tripartite Motif Containing Protein 15 (TRIM15)

Tripartite motif-containing protein 15 is a protein encoded by the TRIM15 gene. TRIM15 is a member of the tripartite motif (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 coiled-coil region. The protein localizes to the cytoplasm. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.A functional genomic approach, based on systematic data gathering, was used to characterize a family of proteins containing a tripartite motif (TRIM). A total of 37 TRIM genes/proteins were studied, 21 of which were novel. The results demonstrate that TRIM proteins share a common function: by means of homo-multimerization they identify specific cell compartments.
