Tyrosine-protein phosphatase non-receptor type 1 also known as protein-tyrosine phosphatase 1B (PTP1B) is an enzyme that is the founding member of the protein tyrosine phosphatase (PTP) family. In humans it is encoded by the PTPN1 gene . [ 5 ]
Protein tyrosine phosphatases (EC 3.1.3.48, systematic name protein-tyrosine-phosphate phosphohydrolase) are a group of enzymes that remove phosphate groups from phosphorylated tyrosine residues on proteins: [a protein]-tyrosine phosphate + H 2 O = [a protein]-tyrosine + phosphate. Protein tyrosine (pTyr) phosphorylation is a common post ...
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. Protein tyrosine phosphatases are protein enzymes that remove phosphate moieties from tyrosine residues on other proteins. Tyrosine kinases are enzymes that add phosphates to tyrosine residues, and are the opposing enzymes to PTPs.
A protein phosphatase is a phosphatase enzyme that removes a phosphate group from the phosphorylated amino acid residue of its substrate protein. Protein phosphorylation is one of the most common forms of reversible protein posttranslational modification ( PTM ), with up to 30% of all proteins being phosphorylated at any given time.
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. Protein tyrosine phosphatases are protein enzymes that remove phosphate moieties from tyrosine residues on other proteins. Tyrosine kinases are enzymes that add
Receptor-type tyrosine-protein phosphatase beta or VE-PTP is an enzyme specifically expressed in endothelial cells that in humans is encoded by the PTPRB gene. [5] [6]
Trodusquemine is an aminosterol (polyamine steroid conjugate) that inhibits protein tyrosine phosphatase 1B (PTP1B) activity. [1] The compound exhibits broad-spectrum antimicrobial activity [2] and numerous regenerative, neuroprotective, anti-atherosclerotic, antitumor, antiangiogenic, antiobesity, and anxiolytic properties.

High levels of protein-tyrosine kinases and phosphatases and their substrates at synapses, both presynaptically and postsynaptically, suggest that tyrosine phosphorylation may regulate synaptic transmission. The role of tyrosine phosphorylation in the regulation of ligand-gated ion channels in the
