CD101 is a disulfide-linked homodimeric polypeptide. The gene encoding the CD101 antigen is identical to the gene encoding for the V7 antigen, which corresponds to a type I transmembrane protein containing seven Ig-like loops in its extracellular domain. CD101 may play an important regulatory role during T cell activation and may also be useful in combination with other markers for the diagnosis of LCH (Langerhans cell histiocytosis). CD101 is expressed on monocytes, granulocytes, dendritic cells and at low levels on a subset of peripheral T-cells comprising both CD4+ and CD8+, as well as both CD45RA+ and CD45RO+ cells. Expression of CD101 increases upon T cell activation.
