The nucleotide sequence of four anti-(Glu60-Ala30-Tyr10)n (GAT) monoclonal gamma 1 heavy chain mRNAs was determined from codon 10 to 120. This sequence overlaps with the NH2-terminal amino acid sequence, allowing elucidation of the complete protein sequence encompassing regions VH, D and JH. These sequences, which are highly conserved, indicate that anti-GAT antibodies expressing the same public idiotypic specificities represent a paucigene system, which uses at least two D-J combinations leading to functionally similar hypervariable regions involved in the recognition of the dominant Glu-Tyr determinant. D regions are encoded by D genes which are closely related either to the D-SP2 or the D.FL16 germ line gene cores.
测定了四种抗(Glu60 - Ala30 - Tyr10)n(GAT)单克隆γ1重链mRNA从第10密码子到第120密码子的核苷酸序列。该序列与NH2末端氨基酸序列重叠,从而能够阐明包含VH、D和JH区域的完整蛋白质序列。这些高度保守的序列表明,表达相同公共独特型特异性的抗GAT抗体代表一个寡基因系统,该系统使用至少两种D - J组合,导致在识别显性Glu - Tyr决定簇中涉及功能相似的高变区。D区域由与D - SP2或D.FL16种系基因核心密切相关的D基因编码。
