ARID2

ARID2 is a subunit of the PBAF chromatin-remodeling complex, which facilitates ligand-dependent transcriptional [[Activator (genetics)|

activation]] by nuclear receptors.

The ARID2 protein contains two conserved C-terminal C2H2 zinc fingers motifs, a region rich in the amino acid residues proline and glutamine, a RFX (regulatory factor X)-type winged-helix DNA-binding domain, and a conserved N-terminal AT-rich DNA interaction domain—the last domain for which the protein is named.

Mutation studies have revealed ARID2 to be a significant tumor suppressor in many cancer subtypes. ARID2 mutations are prevalent in hepatocellular carcinoma{{cite journal | vauthors = Li M, Zhao H, Zhang X, Wood LD, Anders RA, Choti MA, Pawlik TM, Daniel HD, Kannangai R, Offerhaus GJ, Velculescu VE, Wang L, Zhou S, Vogelstein B, Hruban RH, Papadopoulos N, Cai J, Torbenson MS, Kinzler KW | title = Inactivating mutations of the chromatin remodeling gene ARID2 in hepatocellular carcinoma | journal = Nature Genetics | volume = 43 | issue = 9 | pages = 828–9 | date = Sep 2011 | pmid = 21822264 | pmc = 3163746 | doi = 10.1038/ng.903 }} and melanoma.{{cite journal | vauthors = Hodis E, Watson IR, Kryukov GV, Arold ST, Imielinski M, Theurillat JP, Nickerson E, Auclair D, Li L, Place C, Dicara D, Ramos AH, Lawrence MS, Cibulskis K, Sivachenko A, Voet D, Saksena G, Stransky N, Onofrio RC, Winckler W, Ardlie K, Wagle N, Wargo J, Chong K, Morton DL, Stemke-Hale K, Chen G, Noble M, Meyerson M, Ladbury JE, Davies MA, Gershenwald JE, Wagner SN, Hoon DS, Schadendorf D, Lander ES, Gabriel SB, Getz G, Garraway LA, Chin L | title = A landscape of driver mutations in melanoma | journal = Cell | volume = 150 | issue = 2 | pages = 251–63 | date = Jul 2012 | pmid = 22817889 | pmc = 3600117 | doi = 10.1016/j.cell.2012.06.024 }}{{cite journal | vauthors = Krauthammer M, Kong Y, Ha BH, Evans P, Bacchiocchi A, McCusker JP, Cheng E, Davis MJ, Goh G, Choi M, Ariyan S, Narayan D, Dutton-Regester K, Capatana A, Holman EC, Bosenberg M, Sznol M, Kluger HM, Brash DE, Stern DF, Materin MA, Lo RS, Mane S, Ma S, Kidd KK, Hayward NK, Lifton RP, Schlessinger J, Boggon TJ, Halaban R | title = Exome sequencing identifies recurrent somatic RAC1 mutations in melanoma | journal = Nature Genetics | volume = 44 | issue = 9 | pages = 1006–14 | date = Sep 2012 | pmid = 22842228 | pmc = 3432702 | doi = 10.1038/ng.2359 }} Mutations are present in a smaller but significant fraction in a wide range of other tumors.{{cite journal | vauthors = Shain AH, Pollack JR | title = The spectrum of SWI/SNF mutations, ubiquitous in human cancers | journal = PLOS ONE | volume = 8 | issue = 1 | pages = e55119 | year = 2013 | pmid = 23355908 | pmc = 3552954 | doi = 10.1371/journal.pone.0055119 | bibcode = 2013PLoSO...855119S | doi-access = free }} ARID2 mutations are enriched in hepatitis C virus-associated hepatocellular carcinoma in the US and European patient populations compared with the overall mutation frequency.{{cite journal | vauthors = Zhao H, Wang J, Han Y, Huang Z, Ying J, Bi X, Zhao J, Fang Y, Zhou H, Zhou J, Li Z, Zhang Y, Yang X, Yan T, Wang L, Torbenson MS, Cai J | title = ARID2: a new tumor suppressor gene in hepatocellular carcinoma | journal = Oncotarget | volume = 2 | issue = 11 | pages = 886–91 | date = Nov 2011 | pmid = 22095441 | pmc = 3259997 | doi=10.18632/oncotarget.355}}
