Ubiquitin -- as the name suggests -- is found in cells throughout the body. Infact, this 76-amino-acid-long protein appears in nearly identical form in manyother species, even some quite distant from humans on the phylogenic tree. Yeastubiquitin, for example, differs from the human p...Evidence For Earliest Maritime-Based Societies In The Americas Reported In Science Magazine
