ID:KDM2A_HUMAN DESCRIPTION: RecName: Full=Lysine-specific demethylase 2A; EC=1.14.11.27; AltName: Full=CXXC-type zinc finger protein 8; AltName: Full=F-box and leucine-rich repeat protein 11; AltName: Full=F-box protein FBL7; AltName: Full=F-box protein Lilina; AltName: Full=F-box/LRR-repeat protein 11; AltName: Full=JmjC domain-containing histone demethylation protein 1A; AltName: Full=[Histone-H3]-lysine-36 demethylase 1A; FUNCTION: Histone demethylase that specifically demethylates 'Lys- 36' of histone H3, thereby playing a central role in histone code. Preferentially demethylates dimethylated H3 'Lys-36' residue while it has weak or no activity for mono- and tri-methylated H3 'Lys- 36'. May also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. Required to maintain the heterochromatic state. Associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at the centromere. Required to sustain centromeric integrity and genomic stability, particularly during mitosis. CATALYTIC ACTIVITY: Protein N(6),N(6)-dimethyl-L-lysine + 2- oxoglutarate + O(2) = protein N(6)-methyl-L-lysine + succinate + formaldehyde + CO(2). CATALYTIC ACTIVITY: Protein N(6)-methyl-L-lysine + 2-oxoglutarate + O(2) = protein L-lysine + succinate + formaldehyde + CO(2). COFACTOR: Binds 1 Fe(2+) ion per subunit. SUBUNIT: Part of a SCF (SKP1-cullin-F-box) protein ligase complex (By similarity). Interacts with CBX5/HP1A; the interaction promotes CBX5 localization to chromatin. SUBCELLULAR LOCATION: Nucleus, nucleoplasm. Note=Punctate expression throughout the nucleoplasm and enriched in the perinucleolar region. Specifically nucleates at CpG islands where it's presence results in chromatin depleted in H3K36me2. TISSUE SPECIFICITY: Widely expressed, with highest levels in brain, testis and ovary, followed by lung. DOMAIN: The JmjC domain mediates demethylation activity and is required for satellite silencing. DOMAIN: The CXXC zinc finger preferentially recognizes nonmethylated CpG DNA, and binding is blocked when the CpG DNA is methylated. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. SIMILARITY: Belongs to the JHDM1 histone demethylase family. SIMILARITY: Contains 1 CXXC-type zinc finger. SIMILARITY: Contains 1 F-box domain. SIMILARITY: Contains 1 JmjC domain. SIMILARITY: Contains 6 LRR (leucine-rich) repeats. SIMILARITY: Contains 1 PHD-type zinc finger. SEQUENCE CAUTION: Sequence=AAD56012.1; Type=Erroneous initiation; Sequence=BAA76848.2; Type=Erroneous initiation; Sequence=BAB15795.1; Type=Frameshift; Positions=410;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
