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.
