SHP1 also known as PTPN6 belongs to the family of protein tyrosine phosphatases and has a protein mass of approximately 68 kDa. It plays a critical role in cell signaling by dephosphorylating specific targets leading to the modulation of signal transduction pathways. SHP1 is ubiquitously expressed with high levels observed in hematopoietic cells suggesting a specialized function in the immune system.
Biological function summary
SHP1 influences cell proliferation survival and differentiation by acting as a negative regulator of signaling pathways. It is not a part of a larger protein complex but it associates transiently with different receptors and substrates. It plays an important role in the immune response by regulating cytokine signaling which is important for maintaining the balance between immune activation and tolerance.
Pathways
SHP1 significantly impacts the JAK/STAT and B cell receptor signaling pathways. In the JAK/STAT pathway SHP1 interacts with JAK kinases contributing to the downregulation of cytokine signaling. In B cell receptor signaling it associates with Syk influencing immune cell activation and function.
SHP1 has a role in autoimmune diseases such as rheumatoid arthritis and certain types of leukemia. In rheumatoid arthritis defective regulation by SHP1 can lead to excessive inflammation while in leukemia its altered activity impacts cell growth and survival. It interacts with proteins such as STATs and SOCS which are important in these pathologies.
