    • The protein encoded by the human gene HEC ( h ighly e xpressed in c ancer) contains a long series of leucine heptad repeats and appears to be crucial for normal mitosis. HEC localizes to the nuclei of interphase cells and redistributes to centromeres during M phase. Ectopic expression of a mutant HEC containing only the heptad repeats results in the inability of cells to divide more than once. Inactivation of HEC results in disordered sister chromatid alignment and separation, as well as in the formation of nonviable cells with multiple, fragmented micronuclei. HEC interacts through its leucine heptad repeats with several proteins involved in mitosis, including nek2, sb1.8, and two different regulatory subunits of the 26S proteasome, MSS1 and p45. These biochemical properties of HEC suggest its potential roles in modulating proteins important for spindle attachment to kinetochores, sister chromatid movement, and M phase progression.
    • 由人类基因HEC(高表达胰岛素)表达的蛋白质编码的蛋白质含有长序列的亮氨酸七肽重复序列,似乎是 对正常有丝分裂至关重要 HEC定位于相间细胞核,并在M期期间重新分布至着丝粒。 仅含有七重复重复的突变体HEC的异位表达导致细胞不能分裂多于一次。 HEC的失活导致无序的姐妹染色单体比对和分离,以及形成具有多个片段微核的不可维持细胞。 HEC通过其亮氨酸七肽重复与涉及有丝分裂的几种蛋白质相互作用,包括nek2,sb1.8和26S蛋白酶体,MSS1和p45的两个不同调节亚基。 HEC的这些生物化学性质表明其在调节重要的心脏附着到动粒细胞,姐妹染色单体运动和M期进展中的蛋白质的潜在作用。
