WD repeat-containing protein 5 (WDR5), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2-334aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: ATEEKKPETE AARAQPTPSS SATQSKPTPV KPNYALKFTL AGHTKAVSSV KFSPNGEWLA SSSADKLIKI WGAYDGKFEK TISGHKLGIS DVAWSSDSNL LVSASDDKTL KIWDVSSGKC LKTLKGHSNY VFCCNFNPQS NLIVSGSFDE SVRIWDVKTG KCLKTLPAHS DPVSAVHFNR DGSLIVSSSY DGLCRIWDTA SGQCLKTLID DDNPPVSFVK FSPNGKYILA ATLDNTLKLW DYSKGKCLKT YTGHKNEKYC IFANFSVTGG KWIVSGSEDN LVYIWNLQTK EIVQKLQGHT DVVISTACHP TENIIASAAL ENDKTIKLWK SDC. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Contributes to histone modification. May position the N-terminus of histone H3 for efficient trimethylation at 'Lys-4'. As part of the MLL1/MLL complex it is involved in methylation and dimethylation at 'Lys-4' of histone H3. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues. May regulate osteoblasts differentiation.
