KDM2B

The LRR repeats are required for the interaction with the PCGF1-BCORL1 heterodimeric complex.

The JmjC domain mediates demethylation activity (PubMed:17994099). It is also required for repression of ribosomal RNA genes (PubMed:17994099).

The CXXC zinc finger mediates binding to DNA containing unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides.

The F-box domain mediates interaction with UBB.

Histone demethylase that demethylates 'Lys-4' and 'Lys-36' of histone H3, thereby playing a central role in histone code (PubMed:16362057, PubMed:17994099, PubMed:26237645). 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' (PubMed:16362057, PubMed:17994099, PubMed:26237645). Preferentially binds the transcribed region of ribosomal RNA and represses the transcription of ribosomal RNA genes which inhibits cell growth and proliferation (PubMed:16362057, PubMed:17994099). May also serve as a substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex (Probable).

Belongs to the JHDM1 histone demethylase family.
