TIFβ (transcription intermediary factor 1-beta) is an 89 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.

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 1.0 µg/mL. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/mL is recommended. For immunoprecipitation, the suggested use of this reagent is 2.5 µg/test. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
- BioLegend offers two monoclonal antibodies, clones 20A1 and W19027A that bind TIF1β (KAP-1, TRIM28).
- 20A1 is a mouse IgG1, κ isotype; W19027A is a rat IgG2a, κ isotype
- Both clones detect human and mouse TIF1β by western blot; 20A1 binds TIF1β with a higher affinity than W19027A for this application, but also shows a higher background
- Both clones are validated for immunocytochemistry on human cells
- W19027A is validated for immunoprecipitation, 20A1 has not been tested for this application
- Clone W19027A was tested for immunocytochemistry using 4% PFA-fixed HeLa cells permeabilized with either Triton X-100 or methanol. Both methods were compatible with TIF1β staining. - RRID
