这个基因编码一种免疫球蛋白lambda样多肽它位于免疫球蛋白lambda位点内，但不需要体细胞重排来表达。该基因的第一外显子与免疫球蛋白可变基因无关；第二和第三外显子是连接1的免疫球蛋白lambda和免疫球蛋白lambda常数1基因片段。选择性剪接导致多个转录变体[由RefSeq提供，2010年5月]
This gene encodes one of the immunoglobulin lambda-like polypeptides. It is located within the immunoglobulin lambda locus but it does not require somatic rearrangement for expression. The first exon of this gene is unrelated to immunoglobulin variable genes; the second and third exons are the immunoglobulin lambda joining 1 and the immunoglobulin lambda constant 1 gene segments. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]
