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
Chordate from at least as early as the Cambrian explosion. Hemichordata, which includes the acorn worms, has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum. The Hemichordata, along with the Echinodermata (which includes starfish, sea urchins, sea cucumbers, and crinoids), form the Ambulacraria, the sister taxon of the Chordates. The Chordata and Ambulacraria form the superphylum Deuterostomia, composed of the deuterostomes. Attempts to work out the evolutionary relationships of the chordates have produced several hypotheses. The current consensus is that chordates are monophyletic, meaning that the Chordata include all and only the
