Abstract: | Functional screening can reveal a hidden function of a gene. cDNA library-based functional screening has flourished in various fields of biology so far, such as cancer biology, developmental biology and neuroscience. In the postgenomic era, however, various sequence database and public full-length cDNA resources are available, which now allow us to perform more straightforward, gene-oriented screening. Furthermore, the advent of RNA interference techniques has made it possible to perform effective loss-of-function screening. Gene-based functional screening is able to bridge the gap between genes and biological phenomena and raise important biological questions which should be tackled by integration of 'omic' datasets. These possible roles of functional screening will become more and more important in modern molecular biology moving toward the system level understanding of living organisms. |
