Bindin, a major protein of the sea urchin acrosome granule, mediates the species-specific adhesion and binding of sperm to egg required to effect fertilization. We report the isolation and sequence of bindin cDNA clones prepared from Strongylocentrotus purpuratus testis RNA. The bindin gene appears to be productively expressed only in males and only in testes. The protein is produced from a 51-kDa precursor, which is subsequently processed to yield the mature 24-kDa bindin protein.
结合蛋白是海胆顶体颗粒的一种主要蛋白质，它介导精子与卵子的物种特异性黏附及结合，这是实现受精所必需的。我们报道了从紫球海胆睾丸RNA制备的结合蛋白cDNA克隆的分离及序列。结合蛋白基因似乎仅在雄性个体的睾丸中有效表达。该蛋白质由一个51千道尔顿的前体产生，随后经过加工产生成熟的24千道尔顿结合蛋白。
