Recombinant human LSD2 (lysine demethylase 1B, KDM1B), encompassing amino acids 2-822 (end). In this construct the N-terminal end of the protein is fused to GST via a short peptide linker placed between GST consisting of an optimal TEV protease target sequence that allows cleavage of GST (TEV: tobacco etch virus cysteine protease BPS Bioscience #50308). The recombinant protein was affinity purified.
