Background

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 H3K4me1 and Histone H3K4me2, a methylation site associated with transcriptional activation. LSD1 is also involved in transcriptional activation through the demethylation of Histone H3K9me1 and Histone H3K9me2, 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 the study of enzyme kinetics, inhibitor screening, and selectivity profiling.

MALDI-TOF for LSD1 / KDM1A protein activity
3 µM H3K4me2 (1-27aa) peptide was incubated with 5 nM and 15 nM of LSD1 / KDM1A protein in reaction buffer containing 50 mM Tris-HCl pH 8.0, 50 nM FAD for 1 hr at room temperature. Single H3K4me2 peptide was used as negative control. MALDI-TOF was used for detection.
