BTG1（BTG anti-proliferation factor 1），癌症关联基因，基因ID：694，这个基因是一个抗增殖基因家族的成员，它调节细胞的生长和分化。该基因在细胞周期g0/g1期表达最高，在细胞进入g1期时表达下调。编码蛋白与多种核受体相互作用，并作为细胞分化的共同激活因子。该位点与一例b细胞慢性淋巴细胞白血病的t（8；12）（q24；q22）染色体易位有关。[由RefSeq提供，2008年10月]This gene is a member of an anti-proliferative gene family that regulates cell growth and differentiation. Expression of this gene is highest in the G0/G1 phases of the cell cycle and downregulated when cells progressed through G1. The encoded protein interacts with several nuclear receptors， and functions as a coactivator of cell differentiation. This locus has been shown to be involved in a t(8;12)(q24;q22) chromosomal translocation in a case of B-cell chronic lymphocytic leukemia. [provided by RefSeq， Oct 2008]。
