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 CPR3, Kazan, Perigrinibacteria, SM2F11, WS6, and WWE3 were more recently proposed to belong to the larger CPR Group. To complicate matters, it has been suggested that several of these phyla are themselves actually superphyla (see the section on cryptic superphyla below). The proposed superphylum, Terrabacteria, includes Actinobacteria, Cyanobacteria, Deinococcus–Thermus, Chloroflexi, Firmicutes, and candidate phylum OP10. It has been proposed that several of the classes of the phylum Proteobacteria are phyla in their own right, which would make Proteobacteria a superphylum. It was recently proposed that the class Epsilonproteobacteria be combined with the order Desulfurellales to create the new phylum Epsilonbacteraeota.
