Structure of Human PIR1, an Atypical Dual-Specificity Phosphatase
PIR1 is an atypical dual-specificity phosphatase (DSP) that dephosphorylates RNA with a higher specificity than phosphoproteins. Here we report the atomic structure of a catalytically inactive mutant (C152S) of the human PIR1 phosphatase core (PIR1-core, residues 29-205), refined at 1.20 Å resolution. PIR1-core shares structural similarities with DSPs related to Vaccinia virus VH1 and with RNA ...
متن کاملHigh-resolution crystal structure of the catalytic domain of human dual-specificity phosphatase 26.
Dual-specificity phosphatases (DUSPs) play an important role in regulating cellular signalling pathways governing cell growth, differentiation and apoptosis. Human DUSP26 inhibits the apoptosis of cancer cells by dephosphorylating substrates such as p38 and p53. High-resolution crystal structures of the DUSP26 catalytic domain (DUSP26-C) and its C152S mutant [DUSP26-C (C152S)] have been determi...
متن کاملStructure of human dual-specificity phosphatase 27 at 2.38 Å resolution.
There are over 100 genes in the human genome that encode protein tyrosine phosphatases (PTPs) and approximately 60 of these are classified as dual-specificity phosphatases (DUSPs). Although many dual-specificity phosphatases are still not well characterized, novel functions have been discovered for some of them that have led to new insights into a variety of biological processes and the molecul...
متن کاملOverproduction, purification and structure determination of human dual-specificity phosphatase 14.
Dual-specificity phosphatases (DUSPs) are enzymes that participate in the regulation of biological processes such as cell growth, differentiation, transcription and metabolism. A number of DUSPs are able to dephosphorylate phosphorylated serine, threonine and tyrosine residues on mitogen-activated protein kinases (MAPKs) and thus are also classified as MAPK phosphatases (MKPs). As an increasing...
متن کاملStructure of human dual specificity protein phosphatase 23, VHZ, enzyme-substrate/product complex.
Protein phosphorylation plays a crucial role in mitogenic signal transduction and regulation of cell growth and differentiation. Dual specificity protein phosphatase 23 (DUSP23) or VHZ mediates dephosphorylation of phospho-tyrosyl (pTyr) and phospho-seryl/threonyl (pSer/pThr) residues in specific proteins. In vitro, it can dephosphorylate p44ERK1 but not p54SAPK-beta and enhance activation of c...
