AT-rich interactive domain-containing protein 2 (ARID2) is a protein that in humans is encoded by the ARID2 gene.[1]

ARID2 is a subunit of the PBAF chromatin-remodeling complex, which facilitates ligand-dependent transcriptional activation by nuclear receptors.[1]

Structure

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.[2]

Clinical significance

Mutation studies have revealed ARID2 to be a significant tumor suppressor in many cancer subtypes. ARID2 mutations are prevalent in hepatocellular carcinoma[3] and melanoma.[4][5] Mutations are present in a smaller but significant fraction in a wide range of other tumors.[6] ARID2 mutations are enriched in hepatitis C virus-associated hepatocellular carcinoma in the US and European patient populations compared with the overall mutation frequency.[2]

Model organisms

The ARID2 gene, located on chromosome 12q in humans, consists of 21 exons; orthologs are known from mouse, rat, cattle, chicken, and mosquito.[2] Model organisms have been used in the study of ARID2 function. A conditional knockout mouse line, called Arid2tm1a(EUCOMM)Wtsi[11][12] was generated as part of the International Knockout Mouse Consortium program, a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[13][14][15]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[9][16] Twenty six tests were carried out on mutant adult mice and two significant abnormalities were observed.[9] A recessive lethal study found less homozygous mutant embryos during gestation than predicted by Mendelian ratio. In a second study, no homozygous mutant animals survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice; these displayed no abnormalities.[9]
