Partial protein sequences, and DNA sequences of corresponding cDNA and genomic clones were obtained and analyzed to reveal the primary structural features of major, developmentally middle or late components of the B chorion multigene family in Bombyx mori. Comparisons with other types of sequences confirm and clarify the tripartite domain structure of chorion proteins. Glycine-, leucine- and tyrosine-containing, tandemly repetitive peptides form the bulk of the amino-terminal and carboxy-terminal domains ('arms'). Extensive sequence homologies suggest a common evolutionary origin for the amino-terminal arms of some B. mori B sequences and the corresponding portions of members of a different (A) chorion multigene family in Antheraea polyphemus, a distantly related silkmoth.
获得了部分蛋白质序列以及相应cDNA和基因组克隆的DNA序列，并进行了分析，以揭示家蚕B绒毛膜多基因家族主要的、发育中期或晚期成分的一级结构特征。与其他类型序列的比较证实并阐明了绒毛膜蛋白的三方结构域结构。含甘氨酸、亮氨酸和酪氨酸的串联重复肽构成了氨基末端和羧基末端结构域（“臂”）的大部分。广泛的序列同源性表明，家蚕一些B序列的氨基末端臂与远缘相关蚕蛾多音天蚕中不同（A）绒毛膜多基因家族成员的相应部分有着共同的进化起源。
