متن کاملSubcellular Partitioning of Protein Tyrosine Phosphatase 1B to the Endoplasmic Reticulum and Mitochondria Depends Sensitively on the Composition of Its Tail Anchor
The canonical protein tyrosine phosphatase PTP1B is an important regulator of diverse cellular signaling networks. PTP1B has long been thought to exert its influence solely from its perch on the endoplasmic reticulum (ER); however, an additional subpopulation of PTP1B has recently been detected in mitochondria extracted from rat brain tissue. Here, we show that PTP1B's mitochondrial localizatio...
متن کاملLocalization of PTP-1B, SHP-2, and Src exclusively in rat brain mitochondria and functional consequences.
An immunodetection study of protein tyrosine phosphatase 1B (PTP-1B), SHP-2, and Src in isolated mitochondria from different rat tissues (brain, muscle, heart, liver, and kidney) revealed their exclusive localization in the brain. Given this result, we sought whether mitochondria respond to ATP and to the general tyrosine phosphatase inhibitor orthovanadate and found little or no change in the ...
متن کاملRegional Assignment of Ptpre Encoding Protein Tyrosine Phosphataes ε to Mouse Chromosome 7F3
Protein tyrosine phosphatases (PTPases) regulate the tyrosine phosphorylation of target proteins involved in several biological activities including cell proliferation and transformation. Protein tyrosine phosphatase E (PTPE) contains duplicated PTPase-like domains and a short extracellular region. Using the fluorescence in situ hybridization method, the gene encoding PTPE (locus symbol Ptpre...
متن کاملSodium Orthovanadate Treatment Reverses Protracted Methionine Administration Induced Schizophrenia Like Behavior in Rats
Suppression of Akt (Protein kinase B) has been implicated in schizophrenia, the effect which has been documented to be reversed by tyrosine phosphatase inhibition. T hus, present study has been designed to study the effect of sodium orthovanadate, a tyrosine phosphatase inhibitor, on protracted methionine administration induced schizophrenia like behavior in rats. Schizophrenia...
