Human Gene KDM2B (uc001uat.3)
  Description: Homo sapiens lysine (K)-specific demethylase 2B (KDM2B), transcript variant 1, mRNA.
RefSeq Summary (NM_032590): 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. Multiple alternatively spliced transcript variants have been found for this gene, but the full-length nature of some variants has not been determined. [provided by RefSeq, Jul 2008].

DESCRIPTION: RecName: Full=Lysine-specific demethylase 2B; EC=1.14.11.27; AltName: Full=CXXC-type zinc finger protein 2; AltName: Full=F-box and leucine-rich repeat protein 10; AltName: Full=F-box protein FBL10; AltName: Full=F-box/LRR-repeat protein 10; AltName: Full=JmjC domain-containing histone demethylation protein 1B; AltName: Full=Jumonji domain-containing EMSY-interactor methyltransferase motif protein; Short=Protein JEMMA; AltName: Full=Protein-containing CXXC domain 2; AltName: Full=[Histone-H3]-lysine-36 demethylase 1B;
FUNCTION: Histone demethylase that demethylates 'Lys-4' and 'Lys- 36' of histone H3, thereby playing a central role in histone code. Preferentially demethylates trimethylated H3 'Lys-4' and dimethylated H3 'Lys-36' residue while it has weak or no activity for mono- and tri-methylated H3 'Lys-36'. Preferentially binds the transcribed region of ribosomal RNA and represses the transcription of ribosomal RNA genes which inhibits cell growth and proliferation. May also serve as a substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex.
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 (By similarity).
SUBUNIT: Directly interacts with SKP1 and CUL1 (By similarity).
INTERACTION: Q6W2J9:BCOR; NbExp=2; IntAct=EBI-3955564, EBI-950027;
SUBCELLULAR LOCATION: Nucleus, nucleolus.
DOMAIN: The JmjC domain mediates demethylation activity (By similarity). It is also required for repression of ribosomal RNA genes.
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 7 LRR (leucine-rich) repeats.
SIMILARITY: Contains 1 PHD-type zinc finger.

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.
