Mosaic serine proteases in the mammalian central nervous system.

The Role of Mammalian Target of Rapamycine Signaling Pathway in Central Nervous System Cancers: A Review

Mammalian mechanistic target of rapamycine (mTOR) is a conserved serine/threonine kinase in the cellular PI3K/Akt/mTOR signaling pathway. This pathway is modified by cellular alterations such as level of energy, growth factors, stresses, as well as the increased environmental level of cancerous cytokines. In general, increase of this kinase protein function is seen in various types of cancers, ...

Detection of the Keratinolytic Activity of Agriculture and Mount Barker Strain Dermatophilus congolensis Serine Proteases.

Variable and multiple expression of Protease Nexin-1 during mouse organogenesis and nervous system development.

Protease Nexin-1 (PN-1) also known as Glia-Derived Nexin (GDN) inhibits the activity of several serine proteases including thrombin, tissue (tPA)- and urokinase (uPA)-type plasminogen activators. These and other serine proteases seem to play roles in development and tissue homeostasis. To gain insight into where and when PN-1 might counteract serine protease activities in vivo, we examined its ...

Isolation and Characterization of Thermophilic Alkaline Proteases Resistant to Sodium Dodecyl Sulfate and Ethylene Diamine Tetraacetic Acid from Bacillus sp. GUS1

Thermophilic Bacillus sp. GUS1, isolated from  a soil  sample obtained from citrus garden, produced at least three proteases as detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and zymogram analysis. The enzymes were stable in the alkaline pH range (8.0-12.0), with the optimum temperature and pH range of the proteases being 70ºC and 6.0-12.0, respectively. All th...

Mutations in masquerade, a novel serine-protease-like molecule, affect axonal guidance and taste behavior in Drosophila

The masquerade (mas) locus encodes an extracellular molecule with a striking similarity to serine proteases. The serine residue, which is essential for enzymatic activity, has been substituted by glycine, suggesting that MAS could serve to antagonize serine protease activity [Murugasu-Oei et al. (1995), Genes Dev. 9, 139-154]. We describe the expression pattern of mas mRNA and protein in the de...
