What is "neddylation"

n. (context biochemistry English) The process by which the protein http://en.wikipedia.org/wiki/NEDD8 is conjugated to its target proteins, analogous to ubiquitination.

Neddylation is the process by which the ubiquitin-like protein NEDD8 is conjugated to its target proteins. This process is analogous to ubiquitination, although it relies on its own E1 and E2 enzymes. No NEDD8-specific E3 has yet been identified and it is possible that the Neddylation system relies on E3 ligases with dual specificity.
