WebKim et al. (2014) found that human AK2 ( 103020) and DUSP26 formed a complex and that AK2 promoted dephosphorylation of FADD ( 602457) by DUSP26. AK2 enhanced the interaction between DUSP26 and FADD independently of its adenylate kinase activity. Enhanced AK2 expression promoted DUSP26 dephosphorylation of FADD and inhibited … WebThe protein tyrosine phosphatase (PTP) family functions to dephosphorylate the phosphorylated amino acid residues on proteins. The PTP family contains 107 known PTPs divided ... The two PTPN2 isoforms share a phosphotyrosine phosphatase catalytic domain at the N-terminal. PTPN2 negatively regulates the signaling of nonreceptor …
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 + H2O = [a protein]-tyrosine + phosphate Protein … See more Together with tyrosine kinases, PTPs regulate the phosphorylation state of many important signalling molecules, such as the MAP kinase family. PTPs are increasingly viewed as integral components of signal transduction cascades, … See more Individual PTPs may be expressed by all cell types, or their expression may be strictly tissue-specific.
