Paired box (PAX) proteins are a family of transcription factors that play important and diverse roles in animal development (1). Nine PAX proteins (PAX1-9) have been described in humans and other mammals. They are defined by the presence of an amino-terminal "paired" domain, consisting of two helix-turn-helix motifs, with DNA binding activity (2). PAX proteins are classified into four structurally distinct subgroups (I-IV) based on the absence or presence of a carboxy-terminal homeodomain and a central octapeptide region. Subgroup I (PAX1 and 9) contains the octapeptide but lacks the homeodomain; subgroup II (PAX2, 5, and 8) contains the octapeptide and a truncated homeodomain; subgroup III (PAX3 and 7) contains the octapeptide and a complete homeodomain; and subgroup IV (PAX4 and 6) contains a complete homeodomain but lacks the octapeptide region (2). PAX proteins play critically important roles in development by regulating transcriptional networks responsible for embryonic patterning and organogenesis (3); a subset of PAX proteins also maintain functional importance during postnatal development (4). Research studies have implicated genetic mutations that result in aberrant expression of PAX genes in a number of cancer subtypes (1-3), with members of subgroups II and III identified as potential mediators of tumor progression (2).

Paired box (PAX)蛋白是一组在动物发育过程中发挥了重要的及多样性作用的转录因子家族(1)。人和其他哺乳动物中发现了9个PAX蛋白(PAX1-9)。它们都含有氨基端“配对”结构域,包括了2个具有DNA结合活性的螺旋-转角-螺旋模体(2)。PAX蛋白,基于一个羧基端同源域和中心八肽区域的存在与否,可以根据不同的结构分为4个不同的亚型(I-IV)。亚型I (PAX1 和9)包括八肽但是缺乏同源域;亚型II (PAX2, 5, 和 8)包括了八肽和被截短的同源域;亚型III (PAX3 和7)包括了八肽和完整的同源域;和亚型IV (PAX4 和6)包括了一个完整的同源域但是缺乏八肽结构(2)。PAX蛋白在发育过程中发挥了重要作用调控了胚胎模式和器官发生过程中的转录调控网络(3);PAX蛋白的一组亚型还在产后发育过程中发挥重要功能(4)。研究提示基因突变引发的PAX基因表达异常与多种癌症相关(1-3),部分亚型II和III被认为是癌症进程中可能的介导因子(2)。
