這個基因編碼維甲酸受體β，它是核轉錄調控因子甲狀腺類固醇激素受體超家族的成員。這種受體定位于細胞質和亞核室。它與維生素a的生物活性形式維甲酸結合，維甲酸介導胚胎形態發生、細胞生長和分化的細胞信號。人們認為這種蛋白質通過調節基因表達來限制許多細胞類型的生長。該基因首先在一個肝細胞癌中被發現，它位于乙型肝炎病毒整合位點的兩側。交替啟動子的使用和差異剪接導致多個轉錄變體。
This gene encodes retinoic acid receptor beta, a member of the thyroid-steroid hormone receptor superfamily of nuclear transcriptional regulators. This receptor localizes to the cytoplasm and to subnuclear compartments. It binds retinoic acid, the biologically active form of vitamin A which mediates cellular signalling in embryonic morphogenesis, cell growth and differentiation. It is thought that this protein limits growth of many cell types by regulating gene expression. The gene was first identified in a hepatocellular carcinoma where it flanks a hepatitis B virus integration site. Alternate promoter usage and differential splicing result in multiple transcript variants.
