Activity summary

SHP2 also known as PTPN11 is a protein tyrosine phosphatase with a molecular mass of approximately 68 kDa. It is expressed in various tissues including the heart liver and immune cells. SHP2 belongs to the non-receptor class of protein tyrosine phosphatases and plays a critical role in cell signaling by acting as a regulator of signal transduction processes. SHP2 mediates these processes by dephosphorylating specific phosphotyrosine residues on target proteins influencing various cellular functions like proliferation differentiation and survival.

Biological function summary

The role of SHP2 extends to involvement in several signaling cascades such as the Ras/MAPK and PI3K/AKT pathways. It functions as an essential component within protein complexes that facilitate cell communication and response to external signals. The protein modulates growth factor signaling and cytokine signaling highlighting its significance in normal cell function and development. SHP2's statement in signaling processes makes it an important regulator of cellular dynamics.

Pathways

SHP2 participates in the Ras/MAPK and PI3K/AKT signaling pathways which are important for regulating cell growth survival and differentiation. Within these pathways SHP2 interacts with various signaling molecules including Grb2 Sos and Gab family adaptors. These interactions coordinate cellular responses to growth factors and other extracellular cues ensuring proper pathway activation and control. By serving as a critical mediator SHP2 integrates signals that are necessary for appropriate cellular outcomes.

Associated diseases and disorders

SHP2 is associated with several conditions such as Noonan syndrome and various cancers. Mutations in the PTPN11 gene which encodes SHP2 often result in aberrant signaling that leads to developmental anomalies or tumorigenesis. In Noonan syndrome the mutated SHP2 protein results in disrupted Ras/MAPK pathway signaling. As for cancers SHP2 is often found to be overactive leading to enhanced cell proliferation and survival. In these contexts SHP2 is interconnected with other proteins like RAS and RAF which also contribute to oncogenic pathway activation and disease progression.
