The Kank family of proteins, Kank1-Kank4, are characterized by their unique structure, coiled-coil motifs in the N-terminal region, and ankyrin-repeats in the C-terminal region, with an additional motif, the KN motif, at the N-terminus. Kank1 was obtained by positional cloning of a tumor suppressor gene in renal cell carcinoma, while the other members were found by homology search. The family is involved in the regulation of actin polymerization and cell motility through signaling pathways containing PI3K/Akt and/or unidentified modulators/effectors. Their relationship to diseases such as cancer, and to neuronal and developmental disorders, will be an important subject of future study.
Kank蛋白家族(Kank1-Kank4)的特点是具有独特的结构,N端区域有卷曲螺旋基序,C端区域有锚蛋白重复序列,且在N端还有一个额外的基序——KN基序。Kank1是通过对肾细胞癌中一个肿瘤抑制基因进行定位克隆获得的,而其他成员则是通过同源性搜索发现的。该家族通过包含PI3K/Akt和/或未知调节因子/效应器的信号通路参与肌动蛋白聚合和细胞运动的调节。它们与癌症等疾病以及神经和发育障碍的关系将是未来研究的一个重要课题。
