Specificity: If you are looking for a specific domain and are interested in a partial protein or a different isoform, please contact us regarding an individual offer.

Characteristics: Key Benefits:

• Predefined custom protein - from design to production - by highly experienced protein experts.
• Protein expressed in mammalian cells and purified in one-step affinity chromatography
• The optimized expression system ensures reliability for intracellular, secreted and transmembrane proteins.
• State-of-the-art algorithm used for plasmid design (Gene synthesis).

This protein is a predefined protein and will be made for the first time for your order. Our experts in the lab try to ensure that you receive soluble protein.

If you are not interested in a full length protein, please contact us for individual protein fragments.

The big advantage of ordering our predefined custom proteins in comparison to ordering custom-made proteins from other companies is that there is no financial obligation in case the protein cannot be expressed or purified.

Target Details

Target: CBX4 (Chromobox Homolog 4 (CBX4))

Alternative Name: Cbx4

Background: E3 SUMO-protein ligase CBX4 (EC 2.3.2.-) (Chromobox protein homolog 4) (E3 SUMO-protein transferase CBX4) (Polycomb 2 homolog) (Pc2) (mPc2),FUNCTION: E3 SUMO-protein ligase which facilitates SUMO1 conjugation by UBE2I. Involved in the sumoylation of HNRNPK, a p53/TP53 transcriptional coactivator, hence indirectly regulates p53/TP53 transcriptional activation resulting in p21/CDKN1A expression. {ECO:0000250|UniProtKB:O00257}., FUNCTION: Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development (By similarity). PcG PRC1 complex acts via chromatin remodeling and modification of histones, it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility (By similarity). Binds to histone H3 trimethylated at 'Lys-9' (H3K9me3) (PubMed:16537902). Plays a role in the lineage differentiation of the germ layers in embryonic development (PubMed:22226355). {ECO:0000250|UniProtKB:O00257, ECO:0000269|PubMed:16537902, ECO:0000269|PubMed:22226355}.
