Structural Studies of MAP Kinase Cascade Components
MAPK cascade components have been the subject of structural analysis, advancing our understanding of how these enzymes are activated and how they interact. A surprising finding has been that unique inactive co...

WNK1: analysis of protein kinase structure, downstream targets, and potential roles in hypertension
The WNK kinases are a recently discovered family of serine-threonine kinases that have been shown to play an essential role in the regulation of electrolyte homeostasis. Intronic deletions in the WNK1 gene result...

Structure of MAPKs
Mitogen-activated protein kinases (MAPKs) are protein-serine/threonine kinases activated by signaling pathways triggered by developmental stages, cell-surface receptors, cell stresses and other environmental c...

The structure of a Michaelis serpin–protease complex
Serine protease inhibitors (serpins) regulate the activities of circulating proteases. Serpins inhibit proteases by acylating the serine hydroxyl at their active sites. Before deacylation and complete proteoly...

Atomic structure of the MAP kinase ERK2 at 2.3 Å resolution
The structure of the MAP kinase ERK2, a ubiquitous protein kinase target for regulation by Ras and Raf, has been solved in its unphosphorylated low-activity conformation to a resolution of 2.3 A. The two domai...

Structural basis of latency in plasminogen activator inhibitor-1
HUMAN plasminogen activator inhibitor-1 (PAI-1)1,2 is the fast-acting inhibitor of tissue plasminogen activator and urokinase3 and is a member of the serpin family of protease inhibitors4. Serpins normally form c...

Serpin-resistant mutants of human tissue-type plasminogen activator
TISSUE-type plasminogen activator (t-PA) converts the inactive zymogen, plasminogen, into the powerful protease, plasmin, which then degrades the fibrin meshwork of thrombi1–3. To prevent systemic activation of p...
