Lysine-specific demethylase 2A

KDM2A belongs to JHDM1 family of demethylases that contains a JmJC domain. It specifically demethylates H3K36 and is conserved from yeast to humans (PMID: 16362057). KDM2A is found associated with heterochromatic regions of the genome and interacts with the Heterochromatin protein (HP1). It also localises at the centromere and facilitates the silencing of non-coding RNAs that is essential for binding of HP1 to centromere. KDM2A is reported to be downregulated in prostate cancers and is supposed to be involved in the development of carcinomas (PMID: 19001877). It regulates the expression of ribosomal RNA genes via demethylation of H3K36me2 at the promoter under starvation (PMID: 20379134). CpG islands are shown to directly recruit KDM2A to these unmethylated sites so as to differentiate CpG island containing region of chromatin from rest of the genome (PMID: 20417597). NF-kB induces the expression of KDM2A; and KDM2A in turn downregulates NF-kB expression establishing a negative feedback loop in the NF-kB signalling pathway (PMID: 20080798).
