A site of hypersensitivity to DNase I has been found at the 5'-side of the chicken alpha-globin gene domain, ca. 8 Kbp upstream to the first gene. The presence of this site in different types of chicken cells correlates with the transcriptional status of the domain. A matrix attachment region (MAR) has also been found in the same subfragment, suggesting that it may be involved in the control of transcription of the chicken alpha-globin genes.
在鸡α-珠蛋白基因结构域的5'端，即第一个基因上游约8千碱基对处，发现了一个对DNase I敏感的位点。该位点在不同类型鸡细胞中的存在与该结构域的转录状态相关。在同一亚片段中还发现了一个基质附着区域（MAR），这表明它可能参与鸡α-珠蛋白基因转录的调控。
