1.The extracellular matrix surrounding the oocyte before ovulation is called perivitelline membrane in avian species. The perivitelline membrane is constructed with two major glycoproteins, ZPC and ZP1 that are synthesized in the ovarian granulosa cells and the liver, respectively. Although the properties of the major components of the perivitelline membrane had been examined, the knowledge of the nature of fibril formation and secretion pattern from the cell is lacking. In this study, we focused on the binding of quail ZPC and quail ZP1, and comparison of gene structure of various avian species. Moreover, the hypothesis that ZPC binding protein shows an important role for the fibril formation in immature follicle was examined.2.The microsomal fraction of the granulosa cell was immunoblotted with anti-ZPC after SDS-polyacrylamido gel electrophoresis, and a novel protein migrated at 200 kDa was detected. This band was not reacted with anti-ZPC antiserum or anti-ZP1 antiserum, but strongly bind to ZPC. These results indicated the existence of ZPC binding protein for the fibril formation of perivitelline membrane.3.In order to compare the binding affinity of quail ZPC to ZP1 of the various avian species, the gel electrophoresis analysis was performed and found that quail ZPC can bind to other partidge ZP1. Turkey and duck ZP1 was cloned their nucleic acid sequences were determined. The results showed that the protein has variance at C terminal amino acids. Moreover, mutant ZP1 was expressed in CHO-K1 cells, and it is bind to ZPC strongly. These results indicated that the N-terminal proteolytic processing of ZP1 might take place after the arrival of ZP1 at the ovary, and the resulting product is incorporated into the perivitelline membrane in species-specific manner.

1.排卵前周围卵母细胞周围的细胞外基质称为鸟类的细胞膜膜。细胞环膜由分别在卵巢颗粒细胞和肝脏中合成的两个主要糖蛋白ZPC和ZP1构建。尽管已经检查了细胞膜膜的主要成分的特性，但缺乏对细胞原纤维形成和分泌模式的性质的了解。在这项研究中，我们专注于鹌鹑ZPC和鹌鹑ZP1的结合，以及各种鸟类物种的基因结构的比较。此外，研究了ZPC结合蛋白在检查未成熟卵泡中纤维形成的重要作用。该条带与抗ZPC抗血清或抗ZP1抗血清反应，而是与ZPC强烈结合。这些结果表明存在ZPC结合蛋白是对周围膜膜的原纤维形成的存在。3。为了比较各种鸟类物种的Quail ZPC与ZP1的结合亲和力，进行了凝胶电泳分析，并发现Quail Zpc可以与其他Partide ZP1结合。克隆土耳其和鸭ZP1的核酸序列。结果表明该蛋白在C末端氨基酸处具有方差。此外，突变ZP1在CHO-K1细胞中表达，并且强烈与ZPC结合。这些结果表明，ZP1的N末端蛋白水解处理可能发生在ZP1到达卵巢后，并且以物种特异性方式将所得的产物掺入Perivitelline膜中。
