Recombinant LSD1 / KDM1A protein expressed in E. coli cells and supplied in 20 mM Na2HPO4/ NaH2PO4, pH 7.4, 300 mM NaCl, 16 mM glutathione, 1 mM EDTA, 0.05%Tween-20, and 20% glycerol.


LSD1 (Lysine-specific demethylase 1, also designated KDM1A) was identified as a subunit of different complexes (such as CTBP, CoREST, NuRD or BRAF35). LSD1 is involved in transcriptional repression of genes through the demethylation of Histone H3 monomethyl Lys4 and Histone H3 dimethyl Lys4, a methylation site associated with transcriptional activation. LSD1 is also involved in transcriptional activation through the demethylation of Histone H3 monomethyl Lys9 and Histone H3 dimethyl Lys9, a modification often associated with transcriptional repression. LSD1 is also able to demethylate Lys370me1 and Lys370me2 in the regulatory domain of the tumor suppressor p53. LSD1 is a flavin-dependent amine oxidase.

Application Notes

Recombinant LSD1 / KDM1A is suitable for use in histone demethylation assays. A recommended starting point for the demethylation assay is 20-100 ng of recombinant protein per reaction.

Protein Details

LSD1 (KDM1A, AOF2) is a histone demethylase that is specific to histone H3 dimethylated at lysine 4 (H3K4me2). Methylation of H3K4 is a marker of transcriptional activation. Recombinant full-length human LSD1 (GenBank Accession No. NM_015013), amino acids 158-end with N-terminal GST-Tag, was expressed in E. coli. The molecular weight of the protein is 103 kDa. The recombinant protein is >70% pure by SDS-PAGE.
