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 prevents it to be validated, such as where the only evidence is DNA sequence data, even if the whole genome has been sequenced. When the species are members of a whole phylum it is called a candidate division (or candidate phylum) and in 2003 there were 26 candidate phyla out of 52. A candidate phylum was defined by Hugenholtz and Pace in 1998, as a set of 16S ribosomal RNA sequences with less than 85% similarity to already-described phyla. More recently an even lower threshold of 75% was proposed. Three candidate phyla were known before 1998, prior to the 85%
