Ubiquitin branches out.

ABSTRACT

In recent years, there has been a marked expansion of recognized roles for ubiquitin (Ub) in processes other than proteasome-dependent proteolysis, as well as a proliferation of Ub-like proteins that also function through covalent attachment to other proteins. The full diversity of functions for these proteins was on display at the American Society for Cell Biology (ASCB) meeting on "Non-Traditional Functions of Ubiquitin and Ubiquitin-Like Proteins" held at Colorado College in Colorado Springs, Colorado (August 11-14th, 2002).
