Application Notes
Immunofluorescence: Successful usage on mouse embryo at the late zygote stage, 5ug/ml. Strong expression of the protein seen in the nucleus of HeLa and U2OS cells.
ChIP successful usage for K562 cells is reported in scientific literature (PMID: 21170338). WB: Approx. 120 kDa band observed in HepG2 lysates (calculated MW of 88.5 kDa band according to NP_005753.1). The higher observed MW is explained by sumoylated protein.
IHC-P: Human breast shows nuclear staining in epithelial duct cells. IHC successful usage on human gastric cancer surgical specimens is reported in scientific literature (PMID: 19898899).
Flow Cytometry: Flow cytometric analysis of HeLa cells.

Background: KAP1

The KRAB (Kruppel Associated Box) domain is minimally about 45 amino acids in length and is a transcriptional repression domain found in numerous transcription factors. Over 220 KRAB zinc finger protein (KRAB ZFP) genes have been identified in the human genome. These proteins functionally repress transcription via specific interactions with KAP1 (KRAB Associated Protein 1). KAP1 is an 835 amino acid polypeptide that contains a RING finger, B boxes, and a PHD finger. KAP1 has been shown to form complexes with KRAB domain transcription factors and increase the efficiency with which they mediate repression. KAP1 has also been shown to directly interact with HP1 (heterochromatin protein 1) and KRAZ1 (Kruppel associated box containing zinc finger protein 1). KAP1 directly targets KRAZ1 to the foci of centromeric heterochromatin containing HP1alpha, helping to regulate transcriptional repression. Recent studies have shown that KAP1 mutants with the ability to bind KRAB but unable to bind HP1 leads to random distribution of KRAZ1 and strong transcriptional activation.
