Disease

[NEUS_HUMAN] Familial encephalopathy with neuroserpin inclusion bodies. The disease is caused by mutations affecting the gene represented in this entry.

Function

[NEUS_HUMAN] Serine protease inhibitor that inhibits plasminogen activators and plasmin but not thrombin. May be involved in the formation or reorganization of synaptic connections as well as for synaptic plasticity in the adult nervous system. May protect neurons from cell damage by tissue-type plasminogen activator.

Evolutionary Conservation

Publication Abstract from PubMed

Human neuroserpin (hNS) is a protein serine protease inhibitor expressed mainly in the nervous system, where it plays key roles in neural development and plasticity by primarily targeting tissue plasminogen activator (tPA). Four hNS mutations are associated to a form of autosomal dominant dementia, known as familial encephalopathy with neuroserpin inclusion bodies. The medical interest in and the lack of structural information on hNS prompted us to study the crystal structure of native and cleaved hNS, reported here at 3.15 and 1.85 A resolution, respectively. In the light of the three-dimensional structures, we focus on the hNS reactive centre loop in its intact and cleaved conformations relative to the current serpin polymerization models and discuss the protein sites hosting neurodegenerative mutations. On the basis of homologous serpin structures, we suggest the location of a protein surface site that may stabilize the hNS native (metastable) form. In parallel, we present the results of kinetic studies on hNS inhibition of tPA. Our data analysis stresses the instability of the hNS-tPA complex with a dissociation half-life of minutes compared to a half-life of weeks observed for other serpin-cognate protease complexes.
