该基因编码的蛋白是btg/tob家族的一员。这个家族有结构上相关的蛋白质，似乎具有抗增殖的特性。这种编码蛋白参与细胞周期g1/s转换的调控。[由RefSeq提供，2008年7月]
The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein is involved in the regulation of the G1/S transition of the cell cycle. [provided by RefSeq, Jul 2008]
