IRTA1 (Immunoglobulin superfamily Receptor Translocation-Associated 1), otherwise known as Fc-receptor-like 4 (FCRL4) or CD307 d, is a structural member of a family of immunoglobulin-like proteins that mediate the immune response of B-cells. In normal lymphoid tissues IRTA1 is expressed in benign monocytoid B-cells, in some marginal zone cells, and in intraepithelial B-cells. In lymphomas it is expressed by tumor cells involved in lympho-epithelial lesions. In marginal lymphomas, marginal zone B-cells selectively express IRTA1, both in non-neoplastic lymphoid tissues and in malignant lymphomas. This provides the opportunity to accurately diagnose marginal lymphomas with a commercially available antibody. The new anti-IRTA1 antibody secreted from the quartett clone QM005 has the same reactivity and specificity as the anti-IRTA1 antibody produced from the clone MUM2. This was determined through analyzing a large number of biopsies with nodal and extranodal marginalzone lymphomas as well as non-marginalzone lymphomas. As a result, a suitable anti-IRTA1 antibody is now available for the detection of marginal zone lymphoma in lymph nodes and extranodal locations.
