C2orf73 base pairs upstream of "C2orf73". Many of the transcription factors normally regulate processes such as cell development and differentiation, cell death, and the cell cycle. Three proteins have been experimentally determined to interact with C2orf73 through Yeast Two-Hybrid experiments. The function of C2orf73 is currently not well understood by the scientific community or anyone else. There are no paralogs of C2orf73 in the Human genome. Orthologs are found throughout, but are limited to, the phylum Chordata (with a few exceptions in other phyla of the kingdom Animalia, like the "Octopus bimaculoides"). C2orf73 Uncharacterized protein C2orf73 is a protein that in
Bacterial phyla similarity with the other Deferribacteres ("Deferribacter" species and relatives) and is considered a separate phylum by Rappé and Giovannoni. Additionally the placement of the genus "Geovibrio" in the phylum Deferribacteres is debated. With the advent of methods to analyse environmental DNA (metagenomics), the 16S rRNA of an extremely large number of undiscovered species have been found, showing that there are several whole phyla which have no known cultivable representative and that some phyla lack in culture major subdivisions as is the case for Verrucomicrobia and Chloroflexi. The term Candidatus is used for proposed species for which the lack of information
