A sex specific antigen which crossreacts with the mammalian H-Y antigen has been identified on the cell surface of hemocytes from the lobster (Homarus americanus) and the gonadal cells of three insect species. The hemocytes from the male lobster, the testicular cells from the male beetle (P. cornutus), and the ovarian cells from two Orthopteran species (L. maderae and D. punctata) specifically absorbed H-Y antibodies. The specificity of H-Y antibody absorptions by cells from only one sex, suggest that an ancestral H-Y-like antigen may be present in invertebrates which could be engaged in sexual (cellular) recognition events.
在龙虾（美洲螯龙虾）血细胞的细胞表面以及三种昆虫的性腺细胞上，已鉴定出一种与哺乳动物H-Y抗原发生交叉反应的性别特异性抗原。雄性龙虾的血细胞、雄性甲虫（角伪叶甲）的睾丸细胞以及两种直翅目昆虫（马德拉蜚蠊和斑点黑蝗）的卵巢细胞能特异性吸收H-Y抗体。仅来自一个性别的细胞对H-Y抗体的吸收具有特异性，这表明无脊椎动物中可能存在一种原始的类H-Y抗原，它可能参与了性别（细胞）识别事件。
