CD3作为T细胞受体的主要组成成分,将信号传导入细胞内部。我们报道了大西洋鲜编码CD3ζ,CD3γδ和CD3ε的cDNA及其相关基因,并利用real-time RT-PCR分析其组织表达特异性。蛙鱼CD3ζ与哺乳动物相比有较高的序列相似性,由一个短胞外（EX）部分、跨膜（TM）缩氨酸和一个带3个长的免疫酪氨酸受体激活基序（ITAMs）的细胞质（CY）尾组成。编码鲜鱼CD3ζ的基因有7个外显子。CD3γδ（在哺乳动物为CD3g和CD3d）和CD3ε都由I个Ig一样EX基团、1个TM缩氨酸和1个带I个ITAMs的CY尾组成。发现2个完全不同的CD3γδ基因,每个有6个外显子。编码CD3ε的基因有5个外显子。RT-PCR也表明大西洋鲜和褐蹲退化的CD3ε有2个转录本。这个假基因与CD3γδ基因尾对尾,具有典型的CD3ε基因结构,额外多了1个外显子。大西洋蛙鱼的CD3基因在胸腺内高度表达,但CD3ε假基因与完整CD3ε基因相比只有微量表达。
