PTPN11 is a member of the protein tyrosine phosphatase (PTP) family. PTP family members are a group of enzymes that catalyze the removal of phosphate groups from tyrosine residues by the hydrolysis of phosphoric acid monoesters. The activity of PTPs opposite that of kinases and phosphorylases and therefore PTPs play an integral role in many signal transduction pathways. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. PTPN11 is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration.

No additional breast data available.
PTPN11 was one of numerous potential early detection biomarkers specific to triple-negative breast cancer in multiple pathways identified.
- Discovery and preliminary confirmation of novel early detection biomarkers for triple-negative breast cancer using preclinical plasma samples from the Women's Health Initiative observational study.
- Development and validation of sandwich ELISA microarrays with minimal assay interference.
- Plasma biomarker profiles differ depending on breast cancer subtype but RANTES is consistently increased.
