Cells respond to their environment by sensing signals and translating them into changes in gene expression. In recent years, synthetic networks have been designed in both prokaryotic and eukaryotic systems to create new functionalities and for specific applications. In this review, we discuss the challenges associated with engineering signal transduction pathways. Furthermore, we address advant...

Over the past decade variety of hosts and vector systems for recombinant protein expression has increased dramatically. Researchers now select from among mammalian, insect, yeast, prokaryotic hosts, number vectors available use in these organisms continues to grow. With availability cDNAs coding sequencing information, it is certain that other, yet be developed will important future. Despite de...

Antifungal agents are causing different problems in the agriculture industry. Plants are using various defense mechanisms for resistance against fungal pathogens. Some examples of these mechanisms are making physical barriers, producing chemical components and pathogenesis-related proteins such as lipid transfer protein (LTP) and Osmotin which can inhibit the growth of fungi at micro-molar conc...

Streptococcus iniae is a major cause of serious bacterial infections in both fish and human beings. Capsular polysaccharide (CPS) of S. iniae is vital to evade phagocytic clearance of the host and serves as an important protective antigen of S. iniae infection in aquatic animals. The CpsD gene was determined to be highly conservative in capsule polysaccharide operon. Prokaryotic expression of t...

background: the fc receptor like (fcrl) molecules belong to the immunoglobulin (ig) superfamily with potentially immunoregulatoryfunction. among the fcrl family fcrl2 and 4 are predominantly expressed on memory b cells and fcrl1 is a pan- b cell marker. to date, noligand has been identifid for the human fcrl1, 2 and 4 molecules.objectives: cloning, expression, purifiation and structural analysi...
