Specificity

CD45R, also designated CD45 and PTPRC, has been identified as a transmembrane glycoprotein, broadly expressed among hematopoietic cells. Multiple isoforms of CD45R are distributed throughout the immune system according to cell type. These isoforms arise because of alternative splicing of exons 4, 5, and 6. The corresponding protein domains are characterized by the binding of monoclonal antibodies specific for CD45RA (exon 4), CD45RB (exon 5), CD45RC (exon 6) and CD45RO (exons 4 to 6 spliced out). The variation in these isoforms is localized to the extracellular domain of CD45R, while the intracellular domain is conserved. CD45R functions as a phosphor-tyrosine phosphatase. Antibody to CD45 is useful in differential diagnosis of lymphoid tumors from non-hematopoietic undifferentiated neoplasms.

Background: CD45RA

The CD45 molecule is comprised of different glycoproteins ranging from 180-240 kD. Expression of CD45 is found on all hemopoietic cells. Detection of the different isoforms can distinguish between different cell forms i.e. naive T cells and memory T cells. CD45RA is an isoform of the CD45 complex and has restricted expression between different subtypes of lymphoid cells. The functional activity of each CD45 isotype also varies.
