Function

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 (By similarity). Dephosphorylates LYN, and thereby modulates LYN activity.

Activity summary

CD45.1 also known as Leukocyte Common Antigen (LCA) or Protein Tyrosine Phosphatase Receptor Type C (PTPRC) is a protein expressed on the surface of all nucleated hematopoietic cells. It has a molecular mass of approximately 180-220 kDa. This protein acts as a receptor-type protein tyrosine phosphatase. CD45.1 is an essential marker in the immune system particularly found on T cells B cells and other white blood cells. The expression of CD45.1 is seen across leukocytes where it plays a significant role in cell signaling and antigen receptor signaling.

Biological function summary

CD45.1 influences the immune response by modulating signals through antigen receptors. It operates as a single-pass type I membrane protein and is not known to be part of a larger complex. This protein is important in the activation and regulation of T-cells and B-cells by fine-tuning the threshold of signals required for cell activation. The presence of CD45.1 affects multiple processes in adaptive immunity impacting lymphocyte development and their further activation in immune responses.

Pathways

CD45.1 is integral in lymphocyte activation pathways. It influences the T-cell receptor (TCR) and B-cell receptor (BCR) signaling pathways by dephosphorylating specific kinases like Lck and Fyn which are important in initiating TCR and BCR signaling cascades. Moreover CD45.1 interacts with other proteins such as CD3 and CD19 being essential in the regulation of immune response and maintaining proper signaling amplitudes to ensure effective immune function.

Associated diseases and disorders

CD45.1 is intricately linked to autoimmune diseases and leukemia. The protein's dysregulation can lead to improper immune signaling contributing to conditions such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). In leukemia the altered expression of CD45.1 and related proteins such as CD20 often correlates with disease progression and treatment response. Understanding the roles of CD45.1 can facilitate the development of targeted therapies in these contexts.
