ORFeome projects: gateway between genomics and omics

Abstract

The availability of entire genome sequences is expected to revolutionize the way in which biology and medicine are conducted for years to come. However, achieving this promise still requires significant effort in the areas of gene annotation, cloning and expression of thousands of known and heretofore unknown protein-encoding genes. Traditional technologies of manipulating genes are too cumbersome and inefficient when one is dealing with more than a few genes at a time. Entire libraries composed of all protein-encoding open reading frames (ORFs) cloned in highly flexible vectors will be needed to take full advantage of the information found in any genome sequence. The creation of such ORFeome resources using novel technologies for cloning and expressing entire proteomes constitutes an effective gateway from whole genome sequencing efforts to downstream 'omics' applications.
