Flow cytometric analysis of U-937 cells with PTPN11 (phospho Y580) monoclonal antibody, clone 4A2 (APC) (Cat # MAB2337). Unstained and untreated as negative control (blue) or stained and untreated (red) or stained and treated with IFNa plus IL-4 and pervanadate (green).
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains two tandem Src homology-2 domains, which function as phospho-tyrosine binding domains and mediate the interaction of this PTP with its substrates. This PTP 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. Mutations in this gene are a cause of Noonan syndrome as well as acute myeloid leukemia. [provided by RefSeq
