11号染色体上的Hox-2基因座代表了小鼠体内含有同源异型盒的主要基因簇之一。我们已经确定了两个新成员(Hox-2.6和Hox-2.7),它们构成了这个由七个连锁基因组成的簇的一部分,并且Hox-2基因座似乎通过复制和分歧与至少另一个小鼠同源盒簇Hox-1相关。Hox-2.6基因编码一个250个氨基酸的预测蛋白质,它在多个区域与某些老鼠、人类、非洲爪哇和斑马鱼的Homeo结构域蛋白显示出广泛的相似性。果蝇变形基因(Dfd)也有这些相同的相似区域,基于这个序列保守性,我们认为Hox-2.6是脊椎动物DFD样家族的一部分。HOX-2.6在胎儿和成人组织中表达,并在F9畸胎瘤干细胞分化过程中受到调节。对小鼠胚胎的原位杂交分析表明,Hox-2.6表达于外胚层衍生物:脊髓、后脑、背根神经节和第X脑神经节。在中枢神经系统中,表达出现在脊髓的最后部,前界位于后脑的某个区域,在中脑或前脑没有表达。在中胚层结构中,HOX-2.6表达于肾脏、胃和肺的间质以及肠道的纵肌层。在胚胎内胚层的衍生体中未观察到表达。Hox-2.6在中胚层和外胚层中的表达模式都是空间受限的,可能反映了该基因在胚胎对位置线索的反应或建立中的作用。
The Hox-2 locus on chromosome 11 represents one of the major clusters of homeo-box-containing genes in the mouse. We have identified two new members (Hox-2.6 and Hox-2.7), which form part of this cluster of seven linked genes, and it appears that the Hox-2 locus is related by duplication and divergence to at least one other mouse homeo box cluster, Hox-1. The Hox-2.6 gene encodes a predicted protein of 250 amino acids, which displays extensive similarity in multiple regions to certain mouse, human, Xenopus, and zebra fish homeo domain proteins. The Drosophila Deformed (Dfd) gene also shares these same regions of similarity, and based on this sequence conservation, we suggest that Hox-2.6 forms part of a vertebrate 'Dfd-like' family. Hox-2.6 is expressed in fetal and adult tissues and is modulated during the differentiation of F9 teratocarcinoma stem cells. In situ hybridization analysis of mouse embryos shows that the Hox-2.6 is expressed in ectodermal derivatives: spinal cord, hindbrain, dorsal root ganglia, and the Xth cranial ganglia. In the central nervous system, expression is observed in the most posterior parts of the spinal cord, with the anterior limit residing in a region of the hindbrain and no expression in the mid- or forebrain. In mesodermal structures, Hox-2.6 is expressed in the kidney, the mesenchyme of the stomach and lung, and the longitudinal muscle layer of the gut. Expression has not been observed in derivatives of embryonic endoderm. The patterns of Hox-2.6 expression in both mesoderm and ectoderm are spatially restricted and may reflect a role for the gene in the response to or establishment of positional cues in the embryo.
