Heterologous Expression System

A great number of systems are available for the expression of viral structural proteins and analysis of their assembly. These systems include both prokaryotic and eukaryotic environments and the products can be assembled either within the cells or in vitro, using cell lysates or purified components. Table I summarizes the systems that have been used for viral assembly and lists their key advantages and disadvantages. [Pg.4]

Heterologous expression systems comprise prokaryotic organisms (e.g., E. coli) and eukaryotic cells (e.g., yeast, HEK293, Xenopus oocytes), which are used to functionally express foreign genes or cDNAs. [Pg.583]

The Argl37His AVPR2 variant has been the subject of detailed study in heterologous expression systems (123). Vasopressin binds the variant with affinity similar to the wild type however, it fails to stimulate G a. This evidence suggests that the conservation of an arginine at this position is necessary for receptor-coupled G protein activity (115,123,124). [Pg.127]

Human CYPlAl has been expressed in several of the heterologous expression systems including yeast, human lymphoblasts, V79 cells and human fibroblasts. The EROD activity in V79 cells expressing CYPlAl is 50pmol/(mg total protein x min) (Schmalix et al., 1993). In human lymphoblasts, EROD activity of 155 pmol/(mg microsomal protein X min) was obtained (Penman et al., 1994). EROD activity in human fibroblasts expressing CYPlAl cDNA is 1.2pmol/(10 cells x min) or approximately... [Pg.207]
