Humaan MafK antilichaam

The developmentally regulated expression of the globin genes depends on upstream regulatory elements termed locuscontrol regions (LCRs) . LCRs are associated with powerful enhancer activity that is mediated by thetranscription factor NFE2 (nuclear factor erythroid-2) . NFE2 DNA-binding activity consists of aheterodimer containing an 18-kD Maf protein (MafF, MafG or MafK) and p45. Since Maf homodimers lack aputative transactivation domain, the small Mafs behave as transcriptional repressors when they dimerize amongthemselves. However, they seem to serve as transcriptional activators by dimerizing with other (usually larger) basic-zipper proteins and recruiting them to specific DNA-binding sites. Small Maf proteins heterodimerizewith Fos and may act as competitive repressors of the NF-E2 transcription factor. The MafK of Maf proteinsis primarily expressed during development in mesenchymal and hematopoietic cells and neurons.

Can be stored at 2°C to 8°C for 1 week. For long term storage, aliquot and store at -20C to -80C. Avoid repeated freezing and thawing cycles.

Liquid in. Phosphate-Buffered Saline (pH 7.4) with 0.02% Sodium Azide, 10% glycerol

The antibody has been tested by ELISA and Western blot analysis to assure specificity and reactivity. Since application varies, however, each investigation should be titrated by the reagent to obtain optimal results.
