== Function ==
[https://www.uniprot.org/uniprot/KDM5A_HUMAN KDM5A_HUMAN] Histone demethylase that specifically demethylates 'Lys-4' of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-9', H3 'Lys-27', H3 'Lys-36', H3 'Lys-79' or H4 'Lys-20'. Demethylates trimethylated and dimethylated but not monomethylated H3 'Lys-4'. May stimulate transcription mediated by nuclear receptors. May be involved in transcriptional regulation of Hox proteins during cell differentiation. May participate in transcriptional repression of cytokines such as CXCL12. Plays a role in the regulation of the circadian rhythm and in maintaining the normal periodicity of the circadian clock. In a histone demethylase-independent manner, acts as a coactivator of the CLOCK-ARNTL/BMAL1-mediated transcriptional activation of PER1/2 and other clock-controlled genes and increases histone acetylation at PER1/2 promoters by inhibiting the activity of HDAC1 (By similarity).[UniProtKB:Q3UXZ9]<ref>PMID:11358960</ref> <ref>PMID:15949438</ref> <ref>PMID:17320160</ref> <ref>PMID:17320161</ref> <ref>PMID:17320163</ref>

== Publication Abstract from PubMed ==
The histone H3 lysine 4 demethylase RBP2 contains a DNA binding domain, the AT-rich interaction domain (ARID). We solved the structure of ARID by NMR, identified its DNA binding motif (CCGCCC) and characterized the binding contacts. Immunofluorescence and luciferase assays indicated that ARID is required for RBP2 demethylase activity in cells and that DNA recognition is essential to regulate transcription.

The ARID domain of the H3K4 demethylase RBP2 binds to a DNA CCGCCC motif.,Tu S, Teng YC, Yuan C, Wu YT, Chan MY, Cheng AN, Lin PH, Juan LJ, Tsai MD Nat Struct Mol Biol. 2008 Apr;15(4):419-21. Epub 2008 Feb 12. PMID:18270511<ref>PMID:18270511</ref>
