These suggest the bsp proteins and its homologous proteins are ubiquitous in mammals and must have some physical significances . in our research , to find and study the important role of bsp proteinsand their related proteins in the development of zygotes and to find the new gene related to bsp , we cloned a cdna gene sequence related to bsp proteins and make it express in eukaratic cells . the fusion protein acquired are purified are used to deduce its biological functions 而在我们的实验中为了发现和研究bsp及其相关蛋白在受精卵的发育中的重要作用，寻找bsp相关的新基因，克隆了一个与bsp蛋白相关基因的山一na序列并将该基因编码的蛋白质在原核细胞中进行了表达和纯化，将纯化后的融合蛋白作了一些生物学功能方面的初步工作，发现新蛋白对tpk有一定的抑制作用，而tpk是细胞生长和代谢中十分重要的关键酶，这对于进一步研究新蛋白的生物学功能具有十分重要的意义。
