General description
Chromobox homolog 4 (CBX4) is an E3 small ubiquitin-like modifier (SUMO)-protein ligase which belongs to the polycomb group (PcG) of multiproteins.
Immunogen
E3 SUMO-protein ligase CBX4 recombinant protein epitope signature tag (PrEST)
Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
Chromobox homolog 4 (CBX4) is mainly responsible for formation of large multimeric complexes called polycomb group (PcG) bodies which take part in the repression of gene expression. It is involved in the recruitment of the transcriptional corepressor C-terminal binding protein (CtBP) to PcG bodies and promotes its sumoylation. This facilitates the transfer of SUMO (Small ubiquitin-related modifier) to CtBP. CBX4 also covalently modifies Smad-1 interacting protein 1 (SIP1) by sumoylation and hence acts as a SUMO E3 ligase. E-cadherin repression by SIP1 is partially inhibited due to the sumoylation.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

Tumor Protein p53-Induced Nuclear Protein 1 (TP53INP1) is a tumor suppressor that modulates the p53 response to stress. TP53INP1 is one of the key mediators of p53 antioxidant function by promoting the p53 transcriptional activity on its target genes. TP53INP1

Epithelial-mesenchymal transition (EMT) is important in embryonic development and tumorigenesis. Smad-interacting protein 1 (SIP1) can induce EMT by repressing the transcription of E-cadherin through recruitment of the corepressor C-terminal-binding protein (CtBP). How the activity of SIP1 is regulated still remains
