HeLa cells were fixed with 1% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5% Triton X-100 for ten minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2.5 µg/ml anti-TIF1β (KAP-1, TRIM28) (clone 20A1) Alexa Fluor® 647 (red) in 5% FBS, overnight at 4°C, followed by Alexa Fluor® 488 Phalloidin (green) staining for 20 minutes. Nuclei were counterstained with DAPI (blue). The image was captured with a 40X objective.

Description

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.
