ORFeome

In molecular genetics, an ORFeome refers to the complete set of open reading frames (ORFs) in a genome. The term may also be used to describe a set of cloned ORFs.{{Cite book | last1 = Ohara | first1 = O. | chapter = ORFeome Cloning | doi = 10.1007/978-1-60761-232-2_1 | title = Reverse Chemical Genetics | series = Methods in Molecular Biology | volume = 577 | pages = 3–9 | year = 2009 | isbn = 978-1-60761-231-5 | pmid = 19718504 }} ORFs correspond to the protein coding sequences (CDS) of genes. ORFs can be found in genome sequences by computer programs such as GENSCAN and then amplified by PCR. While this is relatively trivial in bacteria the problem is non-trivial in eukaryotic genomes because of the presence of introns and exons as well as splice variants.

Use in research

The usage of complete ORFeomes reflects a new trend in biology that can be succinctly summarized as omics. ORFeomes are used for the study of protein-protein interactions,{{cite journal |vauthors=Titz B, Rajagopala SV, Goll J, Häuser R, McKevitt MT, Palzkill T, Uetz P |title=The binary protein interactome of Treponema pallidum--the syphilis spirochete |journal=PLOS ONE |volume=3 |issue=5 |pages=e2292 |year=2008 |pmid=18509523 |pmc=2386257 |doi=10.1371/journal.pone.0002292 |bibcode=2008PLoSO...3.2292T |editor1-last=Hall |editor1-first=Neil|doi-access=free }} {{open access}}{{cite journal |vauthors=Uetz P, Rajagopala SV, Dong YA, Haas J |title=From ORFeomes to protein interaction maps in viruses |journal=Genome Research |volume=14 |issue=10B |pages=2029–33 |date=Oct 2004 |pmid=15489322 |doi=10.1101/gr.2583304|doi-access=free }} protein microarrays, the study of antigens,{{cite journal |last1=McKevitt |first1=Matthew |last2=Brinkman |first2=Mary Beth |last3=McLoughlin |first3=Melanie |last4=Perez |first4=Carla |last5=Howell |first5=Jerrilyn K. |last6=Weinstock |first6=George M. |last7=Norris |first7=Steven J. |last8=Palzkill |first8=Timothy |date=2005-07-01 |title=Genome scale identification of Treponema pallidum antigens |journal=Infection and Immunity |volume=73 |issue=7 |pages=4445–4450 |doi=10.1128/IAI.73.7.4445-4450.2005 |issn=0019-9567 |pmc=1168556 |pmid=15972547}} and other fields of study.
