Functional genomics involves making use of the vast amount of data produced by genomic projects such as genome sequencing with the aim of describing gene functions and interactions.
Functional genomics focuses on dynamic aspects such as gene transcription, translation, and protein-protein interactions. Functional genomics includes also function-related aspects of the genome itself such as mutation and polymorphism Functional genomics involves measurements of molecular activities, often using high-throughput technologies.
Functional genomics includes, but is not limited to, measurements of transcript levels (transcriptomics), protein levels (proteomics), metabolite levels (metabolomics), protein interactions and studies in model organisms and many other approaches. Bioinformatics is a critial component of functional genomics.
