The protein encoded by this gene 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 function of this protein has not been identified. This gene lies within the major histocompatibility complex class I region on chromosome 6. Alternate splicing results in two transcript variants encoding different isoforms.,TRIM39,RNF23,TFP,TRIM39B,Epigenetics & Nuclear Signaling,Cell Biology & Developmental Biology,Ubiquitin,TRIM39
