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

- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.025 - 0.1 µg per ml. For immunocytochemistry, a concentration range of 2.5 - 10 μg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Additional reported applications (for the relevant formats) include: immunofluorescence1, Western blotting1 and chromatin immunoprecipitation1.
This clone is not recommended for ChIP (Chromatin Immunoprecipitation) assays (as determined by in-house testing).
This clone may produce increased background by western blot when used at concentrations exceeding 0.1 µg/mL.
