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]
A study in humans demonstrated that the IGLL5 exhibited a Gini impurity score of 0, indicating it was present in some pure peripheral blood samples and in one mixture containing blood, while being absent in mixtures without blood, supporting its role as a discriminatory protein for body fluid classification [Shehata et al. DOI:10.1016/j.fsigen.2025.103343].
