    • Identified herein are sperm ligand proteins located in the membrane of sperm, which proteins interact with the membrane of oocytes. Methods of using these proteins, or fragments or derivatives or analogs thereof, are also described. These include methods of increasing (or reducing) successful fertilization, for instance through improved sperm-oocyte binding, fusion or activation (or the blocking thereof); methods of preventing fertilization of an oocyte, for instance by inducing an immune response to at least one sperm ligand that promotes sperm-oocyte binding, sperm-oocyte fusion or oocyte activation; and methods for enhancing assisted reproductive technologies, for instance through stimulation of activation with nuclear transfer, stimulation of inactive or weak sperm, and so forth.
    • 本文所确定的是位于精子膜中的精子配体蛋白,该蛋白质与卵母细胞膜相互作用。 还描述了使用这些蛋白质或其片段或衍生物或类似物的方法。 这些包括增加(或减少)成功受精的方法,例如通过改善的精子卵母细胞结合,融合或活化(或其阻断); 预防卵母细胞受精的方法,例如通过诱导至少一种促进精子卵母细胞结合,精子卵母细胞融合或卵母细胞活化的精子配体的免疫应答; 以及用于增强辅助生殖技术的方法,例如通过用核转移刺激激活,刺激无活性或弱精子等。
