Human Gene KDM2A (uc001ojw.3) Description and Page Index
  Description: Homo sapiens lysine (K)-specific demethylase 2A (KDM2A), transcript variant 1, mRNA.
RefSeq Summary (NM_012308): This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbls class and, in addition to an F-box, contains at least six highly degenerated leucine-rich repeats. This family member plays a role in epigenetic silencing. It nucleates at CpG islands and specifically demethylates both mono- and di-methylated lysine-36 of histone H3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012].

DESCRIPTION: RecName: Full=Lysine-specific demethylase 2A; EC=; 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;

-  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.
