Function
Lysine-specific histone demethylase 1 or 1A (LSD1) is a flavin-dependent oxidase that catalyzes the removal of methyl groups from mono- and dimethylated lysine 4 of histone H3. LSD1 is a nuclear homolog of amine oxidase. LSD contains a SWIRM domain which is a small a-helical domain which binds DNA. It functions as histone demethylase and transcriptional corepressor. LSD1 demethylation occurs via a reaction which produces formaldehyde. LSD1 is a component of transcriptional co-repressor complex which also contains CoREST (co-repressor of element-1-silencing transcription factor)[1].

- Lysine-specific histone demethylase 2 or 1B (LSD2) is a flavin-dependent oxidase that catalyzes the removal of methyl groups from mono- and dimethylated lysine 9 of histone H3.
- Lysine-specific histone demethylase 5A or KDM5A is essential for the repression of astrocyte differentiation[2].
- Lysine-specific histone demethylase 5B or KDM5B or retinoblastoma-binding protein Rbbp2 homolog (LSD5B) is a JmjC domain containing histone demethylase and is an improtant component of DNA repair
Relevance
LSD1 is a potential anti-tumor drug target since it inhibits the tumor suppressor p53[3]. LSD2 demethylation activity helps in increased binding of NF-kB and activation of several inflammatory genes[4]. LSD5B deficiency promotes DNA damage processes[5].
Structural highlights
Human FAD-containing LSD1 with CoREST and histone H3 helix. LSD1 contains several domains: a flexible N-terminal domain, a SWIRM domain (an α-helical domain found in chromosomal proteins mediating protein-protein interactions in chromatin), a substrate and FAD-binding domain, a tower domain (a pair of 2 long anti-parallel helices supporting a 3-helix bundle) and a C-terminal domain[6]. FAD binding site.
