Background: CD45

CD45, also known as leukocyte common antigen (LCA), T200, or Ly5, is a member C of the class 1 receptor-like protein tyrosine phosphatase (PTPRC) family (1, 2). It is a transmembrane glycoprotein which, due to alternative splicing, has a multiple isoforms with a theoretical molecular weight ranging from 180 - 220 kDa (1, 3-5). Human CD45 is synthesized as a 1281 amino acid sequence consisting of an alternatively spliced extracellular receptor-like region, a cysteine-rich domain, fibronectin-like III repeats, a transmembrane segment, and a cytoplasmic region with tandem protein tyrosine phosphatase (PTP) domains: the membrane proximal domain (D1) and the membrane distal domain (D2) (3, 5). CD45 is expressed on all nucleated hematopoietic cells and their precursors, except mature red blood cells, and is one of the most abundantly-expressed cell-surface glycoproteins, comprising approximately 10% of surface proteins in lymphocytes (3). Functionally, CD45 is essential for development and activation of T-cells and B-cells (1-5). More specifically, CD45 positively regulates antigen receptor signaling and Src-family member kinase activity (1, 3). There are many ways to regulate CD45 phosphatase activity including ligand binding, dimerization, protein interactions, cellular localization, and covalent modifications (3, 6). Ligands for CD45 include pUL11, a transmembrane protein of the cytomegalovirus RL11 (CMV RL11) family, and placental protein 14 (PP14), both of which exclusively bind CD45, and various lectins including CD22, galectin-1, galectin-3, macrophage mannose receptor (MR), and macrophage galactose-type lectin (MGL) (6).

Given its role in immune cell development and activation, CD45 has also been linked to a variety of diseases. The importance of CD45 in immunity has been revealed in human and mouse studies where CD45-deficiency leads to a severe-combined immunodeficiency (SCID) phenotype (2, 3, 6). A CD45-knockout mice study revealed inhibited thymocyte production and poor B-cell response, whereas CD45 activation in mice causes lymphoproliferation and autoantibody production (3). CD45 variants have been associated with altered immune function and autoimmune disorders including multiple sclerosis, systemic lupus erythematosus (SLE), and rheumatoid arthritis (6). Furthermore, altered CD45 expression has been implicated in oncological conditions including chronic lymphatic leukemia, acute lymphatic leukemia, Hodgkin lymphoma, multiple myeloma, and diffuse large B-cell lymphoma (6). Considering its role in autoimmune disorders, immunodeficiency and cancer, CD45 is an ideal therapeutic target (3, 6). The main approaches to control CD45 function is through either selective inhibitors or anti-CD45 antibodies (3).

Alternative names for CD45 includes B220, CD antigen: CD45, CD45 antigen, CD45R, EC 3.1.3.48, GP180, LCA, Leukocyte common antigen, LY5, protein tyrosine phosphatase receptor type c polypeptide, PTPRC, receptor-type tyrosine-protein phosphatase C, T200 Glycoprotein, and T200.
