TRIM28 Antibody (PA5-35079) in ICC/IF
Immunocytochemistry analysis of TRIM28 in HeLa cells. Samples were incubated with TRIM28 polyclonal antibody (Product # PA5-35079) using a dilution of 1:25 for 1 h at 37°C followed by Alexa Fluor® 488 conjugated donkey anti-rabbit at a dilution of 1:400 for 50 min at 37°C. Cells were fixed with 4% PFA (20 min) and permeabilized with Triton X-100 (0.1%, 10 min). Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (7 units/mL, 1 h at 37°C). Nuclei were counterstained with DAPI (blue) (10 µg/mL, 10 min). TRI... View More

Target Information
The KRAB (Kruppel-associated box) domain is about 45 amino acids in length and is a transcriptional repression domain found in numerous transcription factors. There have been identified over 220 KRAB-zinc finger protein (KRAB-ZFP) genes in the human genome. These proteins functionally repress transcription via specific interactions with KAP-1 (KRAB-associated protein 1). KAP-1 is an 835 amino acid polypeptide that contains a RING finger, B boxes, and a PHD finger. KAP-1 has been shown to form complexes with KRAB-domain transcription factors and increase the efficiency with which they mediate repression. KAP-1 has also been shown to directly interact with HP1 (heterochromatin protein 1) and KRAZ1 (Kruppel-associated box-containing zinc finger protein 1). KAP-1 directly targets KRAZ1 to the foci of centromeric heterochromatin containing HP1alpha, thus helping to regulate transcriptional repression. Studies have shown that KAP-1 mutants with the ability to bind KRAB but unable to bind HP1 leads to random distribution of KRAZ1 and strong transcriptional activation.
