人bystin是一种与滋养层蛋白直接结合的细胞质蛋白,滋养层蛋白是一种可能参与人胚胎着床的细胞粘附分子。虽然营养素基因是哺乳动物所特有的,但bystin基因(BYSL)在真核生物中是保守的。最近的研究表明,bystin在滋养层细胞由静止的滋养外胚层向活跃的滋养层细胞转变过程中起着关键作用。Bystin基因敲除和敲低实验表明,bystin是必需的胚胎干细胞的存活和滋养外胚层发育的小鼠。此外,bystin在人类癌细胞和小鼠胚胎中的生物化学分析表明其在核糖体生物合成中的功能,特别是在40 S亚基中的18 S RNA的加工中。强有力的证据表明,BYSL是c-MYC的靶标,这与bystin在快速蛋白质合成中的作用一致,这是活跃生长的细胞所必需的。
Human bystin was identified as a cytoplasmic protein directly binding to trophinin, a cell adhesion molecule potentially involved in human embryo implantation. Although the trophinin gene is unique to mammals, the bystin gene (BYSL) is conserved across eukaryotes. Recent studies show that bystin plays a key role during the transition from silent trophectoderm to an active trophoblast upon trophinin-mediated cell adhesion. Bystin gene knockout and knockdown experiments demonstrate that bystin is essential for embryonic stem cell survival and trophectoderm development in the mouse. Furthermore, biochemical analysis of bystin in human cancer cells and mouse embryos indicates a function in ribosomal biogenesis, specifically in processing of 18S RNA in the 40S subunit. Strong evidence that BYSL is a target of c-MYC is consistent with a role for bystin in rapid protein synthesis, which is required for actively growing cells.
