The CyI cytoplasmic actin-encoding genes of Heliocidaris erythrogramma (He), a direct-developing sea urchin, and H. tuberculata, an indirect developer, were isolated and compared to the homologous CyI gene of another indirect developer, Strongylocentrotus purpuratus. Comparisons show that despite the differences in development, the actin gene structures and sequences are highly similar. The coding and 3' untranslated regions are conserved. The 5' He regulatory region has an inserted repeat element, but is otherwise similar to its homologues in the arrangement of presumptive transcription control elements.
对直接发育的海胆红斑海胆（He）和间接发育的瘤海胆的细胞色素I（CyI）细胞质肌动蛋白编码基因进行了分离，并与另一种间接发育的海胆紫球海胆的同源CyI基因进行了比较。比较结果表明，尽管发育方式存在差异，但肌动蛋白基因的结构和序列高度相似。编码区和3'非翻译区是保守的。红斑海胆的5'调控区有一个插入的重复元件，但在推测的转录控制元件的排列上与同源物相似。
