Abstract:
The attempt to develop novel antibiotics, active against organisms resistant to current therapies, has led researchers to seek and explore new drug targets. The rapid sequencing and analysis of entire microbial genomes has identified large numbers of genes that may be sufficiently different from their human counterparts to be exploited as targets for antimicrobial treatment. As a first step, the importance of the various putative targets for microbial growth and survival must be assessed. Emerging validation technologies are becoming increasingly sophisticated and, in certain cases, allow prioritisation of the best targets. In this paper, genetically assisted target evaluation (GATE) is introduced as a versatile target validation technology. GATE concomitantly manipulates both synthesis and stability of the targeted protein using copper ions as an effector. This technology allows rapid quantitation of the lethal consequences of inactivation of targeted gene products in Saccharomyces cerevisiae. Additional tools can then be applied to extend these results into pathogenic organisms, such as Candida albicans.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
Regulation of Expression Occurs at Multiple Steps
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
