Models for Gain-of-Function and Loss-of-Function of MMPsion or losses-of-function. The occasional mutation in the genes for the matrix metalloproteinases or their inhibitors, or polymorphism in their promoters that alter transcriptional regulation has been identified in humans and has helped define the function of these proteins. With ever increasing sop

Expression of MMPs andTIMPs in Mammalian Cells in their functional characterization. Also, transient transfection analysis of promoter constructs driving CAT or luciferase reporter genes is a mainstay of gene regulation studies. One of the critical advantages of mammalian expression over bacterial systems for production of functional proteins i

Expression of Recombinant Matrix Metalloproteinases in Yeastiveness, time considerations). Of course, the final judgment of practicality is determined by the production of sufficient quantities of functional MMPs. A system that combines the benefits of bacterial and cultured cell systems, without their disadvantages, would be of great use.

Refolding of TIMP-2 from Escherichia coli Inclusion Bodiesdoes not require extensive expertise. The major drawback of . as an expression host is the inability of the organism to carry out many posttrans-lational modifications, including glycosylation and disulphide bond formation. High-level intracellular expression of many mammalian proteins in . results

Expression and Refolding of Full-Length HumanTIMP-1 proteins are not sufficiently abundant in their natural state to be used as the primary source, and so it is essential for recombinant protein to be expressed in an appropriate system. In many cases the preferred expression system is . for ease of handling, generally high yields and, where the prot
