Mammalian fertilization is a multi-step process with different requirements for specificity at each step. In the present report we have examined the binding of spermatozoa to homologous and heterologous zonae pellucidae. The homologous zona binding proteins (ZBP) of ejaculated rabbit, pig and human spermatozoa and epididymal mouse spermatozoa have been identified. The rabbit's ZBPs have relative molecular weights (MW) of 32K, 18K, 16K and 14K; the pig's major ZBP is 16K while human spermatozoa bind human zona protein at 17K and 18K. Mouse sperm ZBPs are 19K, 18K and 16K.
哺乳动物受精是一个多步骤过程，每个步骤对特异性都有不同要求。在本报告中，我们研究了精子与同源和异源透明带的结合。已鉴定出射精的兔、猪和人类精子以及附睾小鼠精子的同源透明带结合蛋白（ZBP）。兔的ZBP相对分子量（MW）为32K、18K、16K和14K；猪的主要ZBP为16K，而人类精子在17K和18K处结合人透明带蛋白。小鼠精子ZBP为19K、18K和16K。
