TIFβ (transcription intermediary factor 1-beta) is an 88 kD member of the tripartite motif family. This protein contains three zinc binding domains, a RING domain, a B-box type 1 and type 2 domain, and a coiled-coil region. TIFβ is found in the nucleus and associates with specific chromatin regions. This protein forms a complex with KRAB-domain transcription factors and recruits SETDB1 to histone 3 to increase KRAB-mediated transcriptional repression. TIF1β has been reported to interact with SETDB1 and CBX3 proteins. Studies using knockout mice reveal the important function of TIF1β in regulating genomic imprinting, T cell activation, and T cell tolerance.Product Details
