识别串行
识别串行(英语:recognition sequence),有时也被称为识别位点(英语:recognition site)of any DNA-binding protein motif that exhibits binding specificity, refers to the 核酸串行 (or subset thereof), to which the domain is specific. Recognition sequences are palindromes .
以转录因子 Sp1 为例,能结合于串行 5'-(G/T)GGGCGG(G/A)(G/A)(C/T)-3', 此处 (G/T) indicates that the domain will bind a guanine or thymine at this position.
