Histone demethylase KDM1A (also known as LSD1) is recruited to estrogen-responsive promoters and enhancers in a manner that depends on the HAR domain of HIST1H2AC. KDM1A removes the repressive H3K9me2 epigenetic mark, and consistent with this, KDM1A knockdown leads to abrogated expression of BCL2 and MYC genes in response to estrogen stimulation (Perillo et al, 2008; Su et al, 2014; Wang et al, 2009; Wissmann et al, 2007)

PKN1-mediated phosphorylation of histone H3 threonine residue T12 (also labeled in literature as Thr11) enables demethylation of histone H3 lysine K10 (also labeled in literature as K9) by demethylase KDM1A (LSD1) (Metzger et al. 2008). KDM1A acts on dimethylated and monomethylated H3K9 at AR-regulated promoters (Metzger et al. 2005), so it is shown that KDM1A-mediated demethylation of monomethylated H3K9 (MeK-10-H3) happens sequentially after KDM1A-mediated demethylation of dimethylated H3K9 (Me2K-10-H3).

PKN1, activated by phosphorylation at threonine T774, binds activated AR (androgen receptor) and promotes transcription from AR-regulated promoters. On one hand, phosphorylated PKN1 promotes the formation of a functional complex of AR with the transcriptional coactivator NCOA2 (TIF2) (Metzger et al. 2003). On the other hand, binding of phosphorylated PKN1, in complex with the activated AR, to androgen-reponsive promoters of KLK2 and KLK3 (PSA) genes, leads to PKN1-mediated histone phosphorylation. PKN1-phosphorylated histones recruit histone demethylases KDM4C (JMJD2C) and KDM1A (LSD1), and the ensuing demethylation of histones associated with the promoter regions of KLK2 and KLK3 genes increases their transcription (Metzger et al. 2005, Metzger et al. 2008).

Olfactory receptors (ORs) are 7-pass transmembrane G protein-coupled receptors (GPCRs) located on dendritic cilia of olfactory sensory neurons (OSNs) of the olfactory epithelium (reviewed in Persuy et al. 2015). ORs are also located on cells of some other tissues (reviewed in Oh 2015). ORs bind ligands, called odorants, and activate downstream signaling through a heterotrimeric G-protein leading to opening of olfactory cyclic nucleotide-gated channels (CNG channels) and depolarization of the OSN. The human genome contains about 857 OR genes of which about 394 appear to be capable of encoding a functional OR. The remaining putative OR genes appear to be pseudogenes functionally inactivated by mutations.
Each OR binds a particular odorant or family of odorants. In order to provide odor discrimination, each OSN expresses only one OR gene and connects to specific olfactory bulb glomeruli according to the specific OR expressed (reviewed in Monahan and Lomvardas 2015, McClintock et al. 2020, Sakano et al. 2020). The choice of which OR gene to express is made by an epigenetic mechanism (reviewed in Bashkirova and Lomvardas 2019). Initially during OSN development, OR genes are heterochromatic. A few OR genes become weakly expressed and one then becomes dominant while all other OR genes remain silenced by heterochromatin. During activation of an OR gene, LHX2, LDB1, and EBF1 bind several (~60) intergenic enhancers located between OR genes on 18 chromosomes. The LHX2:LDB1:EBF1:enhancer complexes assemble into an interchromosomal super-enhancer that associates with the expressed OR gene and drives transcription.
Accumulation of OR protein in the endoplasmic reticulum membrane activates the unfolded protein response (UPR) that activates translation of ADCY3, which downregulates the histone methyltransferase KDM1A (LSD1) thereby preventing activation of any other OR genes (Lyons et al. 2013, Dalton et al. 2013).
Most OR proteins are inefficiently translocated from the endoplasmic reticulum membrane to the plasma membrane when they are expressed in heterologous cells. OSNs contain specific proteins that act as chaperones to increase subcellular translocation of at least some ORs (reviewed in Mainland and Matsunami 2012). The short isoform of RTP1 (RTP1S) and RTP2 bind the OR in the endoplasmic reticulum, are translocated with the OR to the plasma membrane, and remain at the plasma membrane. REEP1 more weakly increases translocation of ORs by an uncharacterized mechanism.

Histone lysine demethylases (KDMs) are able to reverse N-methylations of histones and probably other proteins. To date KDMs have been demonstrated to catalyse demethylation of N-epsilon methylated lysine residues. Biochemically there are two distinct groups of N-epsilon methylated lysine demethylases with different catalytic mechanisms, both of which result in methyl group oxidation to produce formaldhyde. KDM1A, formerly known as Lysine Specific Demethylase 1 (LSD1), belongs to the flavin adenine dinucleotide (FAD)-dependent amino oxidase family. The KDM1A reaction mechanism requires a protonatable lysine epsilon-amine group, not available in trimethylated lysines, which consequently are not KDM1 substrates. Other KDMs belong to the Jumonji C (JmjC) -domain containing family. These are members of the Cupin superfamily of mononuclear Fe (II)-dependent oxygenases, which are characterised by the presence of a double-stranded beta-helix core fold. They require 2-oxoglutarate (2OG) and molecular oxygen as co-substrates, producing, in addition to formaldehyde, succinate and carbon dioxide. This hydroxylation-based mechanism does not require a protonatable lysine epsilon-amine group and consequently JmjC-containing demethylases are able to demethylate tri-, di- and monomethylated lysines.
The coordinates of post-translational modifications represented and described here follow UniProt standard practice whereby coordinates refer to the translated protein before any further processing. Histone literature typically refers to coordinates of the protein after the initiating methionine has been removed. Therefore the coordinates of post-translated residues in the Reactome database and described here are frequently +1 when compared with the literature.
In general, methylation at histone H3 lysine-5 (H3K4) and lysine-37 (H3K36), including di- and trimethylation at these sites, has been linked to actively transcribed genes (reviewed in Martin & Zhang 2005). In contrast, lysine-10 (H3K9) promoter methylation is considered a repressive mark for euchromatic genes and is also one of the landmark modifications associated with heterochromatin (Peters et al. 2002).
The first reported JmjC-containing demethylases were KDM2A/B (JHDM1A/B, FBXL11/10). These catalyse demethylation of histone H3 lysine-37 when mono- or di-methylated (H3K36Me1/2) (Tsukada et al. 2006). They were found to contain a JmjC catalytic domain, previously implicated in chromatin-dependent functions (Clissold & Ponting 2001). Subsequently, many other JmjC enzymes have been identified and discovered to have lysine demethylase activities with distinct methylation site and state specificities.
KDM3A/B (JHDM2A/B) are specific for mono or di-methylated lysine-10 on histone H3 (H3K9Me1/2) (Yamane et al. 2006, Kim et al. 2012). KDM4A-C (JMJD2A-C/JHDM3A-C) catalyse demethylation of di- or tri-methylated histone H3 at lysine-10 (H3K9Me2/3) (Cloos et al. 2006, Fodor et al. 2006), with a strong preference for Me3 (Whetstine et al. 2007). KDM4D (JMJD2D) also catalyses demethylation of H3K9Me2/3 (Whetstine et al. 2007). KDM4A-C (JHDM3A-C) can also catalyse demethylation of lysine-37 of histone H3 (H3K36Me2/3) (Klose et al. 2006). KDM5A-D (JARID1A-D) catalyses demethylation of di- or tri-methylated lysine-5 of histone H3 (H3K4Me2/3) (Christensen et al. 2007, Klose et al. 2007, Lee et al. 2007, Secombe et al. 2007, Seward et al. 2007, Iwase et al. 2007). KDM6A and KDM6B (UTX/JMJD3) catalyse demethylation of di- or tri-methylated lysine-28 of histone H3 (H3K27Me2/3) (Agger et al. 2007, Cho et al. 2007, De Santra et al. 2007, Lan et al. 2007, Lee et al. 2007).

KDM7A (KIAA1718/JHDM1D) catalyses demethylation of mono- or di-methylated lysine-10 of histone H3 (H3K9Me1/2) and mono- and di-methylated lysine-28 of histone H3 (H3K27Me1/2) (Horton et al. 2010, Huang et al. 2010). PHF8 (JHDM1E) catalyses demethylation of mono- or di-methylated lysine-10 of histone H3 (H3K9Me1/2) and mono-methylated lysine-21 of histone H4 (H4K20Me1) (Loenarz et al. 2010, Horton et al. 2010, Feng et al. 2010, Kleine-Kohlbrecher et al. 2010, Fortschegger et al. 2010, Qi et al. 2010, Liu et al. 2010). PHF2 (JHDM1E) catalyses demethylation of mono- or di-methylated lysine-10 of histone H3 (H3K9Me1/2) (Wen et al, 2010, Baba et al. 2011). JMJD6 was initially characterized as an arginine demethylase that catalyses demethylation of mono or di methylated arginine 3 of histone H3 (H3R2Me1/2) and arginine 4 of histone H4 (H4R3Me1/2) (Chang et al. 2007) although it was subsequently also characterized as a lysine hydroxylase (Webby et al. 2009).
