Abstract

The N-end rule relates the in vivo half-life of a protein to the identity of its N-terminal residue. Similar but distinct versions of the N-end rule operate in all organisms examined, from mammals to fungi and bacteria. In eukaryotes, the N-end rule pathway is a part of the ubiquitin system. Ubiquitin is a 76-residue protein whose covalent conjugation to other proteins plays a role in many biological processes, including cell growth and differentiation. I discuss the current understanding of the N-end rule pathway.
