Three new human lambda L chain-like Ig genes are identified by restriction enzyme and nucleotide sequence analysis. Two genes, 14.1 and 16.1, have intact J and C regions, and are potentially functional, with open reading frames. A third gene, 18.1, is a pseudogene. The evolutionary lineage of these genes compared to the known functional locus lambda C1-lambda C6 can be surmised from Southern blot and nucleotide homologies. This study demonstrates that the human lambda gene family is more complex than previously recognized.
通过限制性内切酶和核苷酸序列分析鉴定出三个新的人类λ轻链样免疫球蛋白基因。两个基因,即14.1和16.1,具有完整的J区和C区,并且由于具有开放阅读框而具有潜在功能。第三个基因,18.1,是一个假基因。通过Southern印迹和核苷酸同源性可以推测出这些基因与已知的功能性基因座λC1-λC6相比的进化谱系。这项研究表明,人类λ基因家族比以前认识到的更为复杂。
