1. Like calmodulin and troponin c , caltractin contains four potential calcium - binding sites of predicted helix - loop - helix or ef - hand structure . with the development of technology in biology , more and more academicians study questions for discussion by mutating genes in organisms
   中心蛋白的結(jié)構(gòu)類似于鈣調(diào)蛋白、肌鈣蛋白c的結(jié)構(gòu)，含有四個ef - hand ( helix - loop - helix )結(jié)構(gòu)，即四個鈣結(jié)合位點。
2. Rt - pcr revealed that two basic helix - loop - helix ( bhlh ) genes , mash - 1 and ngn - 1 , were up - regulated during the differentiation stage of wnt - 1 - overexpressing p19 cells . these results suggest that the wnt - 1 gene promotes neuronal differentiation and inhibits gliogenesis during the neural differentiation of p19 cells , and that neural bhlh genes might be involved in this process
   我們的實驗結(jié)果提示， wnt - 1基因可能參與了p19細胞神經(jīng)分化過程中的命運決定， wnt - 1基因能促進神經(jīng)元細胞的分化，而抑制神經(jīng)膠質(zhì)細胞的產(chǎn)生；神經(jīng)bhlh基因可能與p19細胞神經(jīng)命運決定和神經(jīng)細胞分化有關(guān)。
