摘要: KCTD1(potassium channel tetramerization domain containing 1)属于钾离子通道四聚化结构域蛋白基因家族的成员,该家族成员的N端具有保守的BTB(Bric-a-brack, Tram-track, Broad complex)结构域和一个钾离子四聚体通道结构域(K-ketra),但C端是多变的。人类KCTD基因家族成员的突变和表达异常与多种疾病相关。研究选取人类皮肤-耳朵-乳头综合征(Scalp-Ear-Nipple Syndrome,SEN)致病基因KCTD1在斑马鱼(Danio rerio)中的直系同源基因kctd1,利用CRISPR/Cas9技术进行基因敲除,通过F1剪尾检测和F1内交,成功获得kctd1 F2纯合突变体。获得的突变体类型为+7 bp和-8 bp。研究结果对于人类KCTD1基因功能以及KCTD1致病机理的研究具有参考价值。

Abstract: KCTD1(potassium channel tetramerization domain containing 1) is one of the members of the potassium channel tetramerization domain containing gene family. The proteins in the gene family possess conserved domains including BTB/POZ domain and K-ketra at the N-terminal, and a variable C-terminal. Mutations and improper expression of human KCTD genes are associated with a variety of diseases. We knocked out the kctd1 gene, the orthologue of human KCTD1, mutation of which caused SEN syndrome in zebrafish(Danio rerio) via CRISPR/Cas9. Two types of homozygous mutants +7 bp and-8 bp were obtained after heterozygous F1 screening and F1 in-cross. This research is of great significance for studying the function of KCTD1 gene and the pathogenesis of KCTD1.
