ID:PTN6_HUMAN DESCRIPTION: RecName: Full=Tyrosine-protein phosphatase non-receptor type 6; EC=3.1.3.48; AltName: Full=Hematopoietic cell protein-tyrosine phosphatase; AltName: Full=Protein-tyrosine phosphatase 1C; Short=PTP-1C; AltName: Full=Protein-tyrosine phosphatase SHP-1; AltName: Full=SH-PTP1; FUNCTION: Modulates signaling by tyrosine phosphorylated cell surface receptors such as KIT and the EGF receptor/EGFR. The SH2 regions may interact with other cellular components to modulate its own phosphatase activity against interacting substrates. Together with MTUS1, induces UBE2V2 expression upon angiotensin II stimulation. Plays a key role in hematopoiesis. CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate. SUBUNIT: Monomer. Interacts with MTUS1 (By similarity). Interacts with MILR1 (tyrosine-phosphorylated). Interacts with KIT (By similarity). Binds PTPNS1, LILRB1 and LILRB2. Interacts with FCRL2, FCRL3, FCRL4, CD300LF, CDK2 and CD84. Interacts with KIR2DL1; the interaction is enhanced by ARRB2. Interacts (via SH2 1 domain) with ROS1; the interaction is direct and promotes ROS1 dephosphorylation. Interacts with EGFR; inhibits EGFR-dependent activation of MAPK/ERK. Interacts with LYN. Interacts with the tyrosine phosphorylated form of PDPK1. INTERACTION: P20273:CD22; NbExp=4; IntAct=EBI-78260, EBI-78277; P11049:CD37; NbExp=4; IntAct=EBI-78260, EBI-6139068; Q9UKJ1:PILRA; NbExp=5; IntAct=EBI-78260, EBI-965833; SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=In neurons, translocates into the nucleus after treatment with angiotensin II (By similarity). Shuttles between the cytoplasm and nucleus via its association with PDPK1. TISSUE SPECIFICITY: Isoform 1 is expressed in hematopoietic cells. Isoform 2 is expressed in non-hematopoietic cells. DOMAIN: The N-terminal SH2 domain functions as an auto-inhibitory domain, blocking the catalytic domain in the ligand-free close conformation. PTM: Phosphorylated on tyrosine residues. Binding of KITLG/SCF to KIT increases tyrosine phosphorylation (By similarity). Phosphorylation at Tyr-564 enhances phosphatase activity. SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-receptor class 2 subfamily. SIMILARITY: Contains 2 SH2 domains. SIMILARITY: Contains 1 tyrosine-protein phosphatase domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
