Target Background

Protein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN. Dephosphorylates LYN, and thereby modulates LYN activity.

  1. Inhibition by high CD45 on CD8(+) T cells may protect against overt T-cell receptor (TCR) auto-MHC reactivity. PMID: 27841348
  2. this study shows that CD45 positioning within lipid rafts is modified during their oncogenic transformation to acute myeloid leukemia PMID: 27579617
