Two repetitive elements of the chicken CR1 family, each located in the 5' flanking region of the avidin-related genes Avr4 and Avr5, have been cloned and sequenced. Both elements are 721 bp in length with 72% identity to a CR1 consensus sequence. They had a 191 bp deletion in a region corresponding to the functional silencer regions previously detected within the CR1 elements upstream of the chicken lysozyme and apoVLDLII genes.
鸡CR1家族的两个重复元件已被克隆和测序，它们分别位于抗生物素蛋白相关基因Avr4和Avr5的5'侧翼区域。这两个元件长度均为721 bp，与CR1共有序列的一致性为72%。在与先前在鸡溶菌酶和载脂蛋白VLDLII基因上游的CR1元件中检测到的功能沉默区域相对应的区域，它们有一个191 bp的缺失。
