A summary of the results for each selenoprotein and selenoprotein factor in all completely sequenced insect genomes.

Species lacking selenoproteins are shown in bold. “+” means the gene was present and conserved, “Cys” means the gene was found as a cysteine homolog, “−” means the gene was absent and “-(?)” means that a candidate could be found but the conservation, or score in the case of tRNASec was too low for it to be considered a bona fide homolog.
*Except for D.persimilis, see text.

缺乏硒蛋白的物种以粗体显示。其中"+"表示该基因存在且保守；"Cys"表示该基因以半胱氨酸同源物的形式被检出；"−"表示该基因缺失；"-(?)"表示可找到候选同源物，但保守性（若为tRNASec则指对应评分）过低，不足以认定为真正的同源物。
*除D.persimilis外，详见正文。
