摘要本文报告在中国大陆发现的10个快速异常血红蛋白系的研究结果，这种异常血红蛋白的电泳迁移移率属于K型，血红蛋白稳定性轻度降低，血红蛋白变型的结构分析，包括珠蛋白肽链的分离，氨基乙基化β链的酶解和指纹分析，以及异常肽段的氨基酸组成和顺序测定，证实其β链113位(G15)的缬氨酸被谷氨酸替代，称为血红蛋白New York(αβ(G15)ValξGlu).
在10个家系的调查中共发现35例H...
Sox基因家族是在动物中发现的一类新的编码转录因子的基因家族，其产物具有一个HMG基序保守区，参与诸如性别决定、骨组织的发育、血细胞生成、神经系统的发育、晶状体的发育等多种早期胚胎发育过程。人类SOX基因的突变或缺失会导致发育异常和严重的先天性疾病。SOX蛋白与其他转录因子相互作用形成复合体而发挥作用。同一Sox基因在不同的细胞或在同一细胞中对不同的启动子具有不同的影响。部分Sox基因之间在功能上...
