What is the official name of the PTPN11 gene?
The official name of this gene is “protein tyrosine phosphatase, non-receptor type 11.”
PTPN11 is the gene's official symbol. The PTPN11 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the PTPN11 gene?
The PTPN11 gene carries the instructions for making a protein called SHP-2. This protein helps control (regulate) the activation of the RAS/MAPK signaling pathway, which helps control several important cell functions. Specifically, it regulates the growth and division of cells (proliferation), the process by which cells mature to carry out specific functions (differentiation), cell movement (migration), and the self-destruction of cells (apoptosis). During embryonic development, the SHP-2 protein is critical in the development of the heart, blood cells, bones, and several other tissues.
The PTPN11 gene belongs to a class of genes known as oncogenes. When mutated, oncogenes have the potential to cause normal cells to become cancerous.
Does the PTPN11 gene share characteristics with other genes?
The PTPN11 gene belongs to a family of genes called PTP (protein tyrosine phosphatases).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
