MKP-5 (DUSP10) is a dual-specificity phosphatase that binds to p38 and SAPK/JNK but not MAPK/ERK, and selectively inactivates p38 and SAPK/JNK (with p38 as preferred substrate), while being present evenly in both cytoplasm and nucleus. |

Crystal structures of the MAP kinase binding domain (BD) and catalytic domain (CD) of human MKP5 were solved at up to 2.2 Å resolution. The BD of MKP5 differs dramatically from MKP3: the cluster of positively charged residues critical for MAPK binding is alpha-helical in MKP5 (vs. loop/beta-strand in MKP3), located 25 Å apart, consistent with distinct substrate preferences. The CD is in an active conformation. |

Crystal structure of p38α in complex with the MAPK binding domain (KBD) of MKP5 at 2.7 Å resolution revealed a bipartite binding mode in which two distinct helical regions of KBD engage the p38α docking site (on the back of the active site), distinct from the classical linear docking motif. The KBD of MKP7 closely resembles MKP5 KBD, suggesting this mechanism is conserved in the cytoplasmic p38/JNK-specific MKP subgroup. |

An allosteric binding pocket on MKP5 (distinct from the active site) was identified; a small-molecule inhibitor binding to this pocket collapses the MKP5 active site and limits MAPK binding. Crystal structure of MKP5 in complex with the inhibitor was solved. The inhibitor recapitulates MKP5 deficiency (activating p38 MAPK and JNK) and blocks TGF-β1-mediated Smad2 phosphorylation in muscle. |
