While there are many types of different degrons, and a high degree of variability even within these groups, degrons are all similar for their involvement in regulating the rate of a protein's degradation. Much like protein degradation (see proteolysis), mechanisms are categorized by their dependence or lack thereof on ubiquitin, a small protein involved in proteasomal protein degradation, Degrons may also be referred to as “ubiquitin-dependent" or “ubiquitin-independent".
Degrons are proteins that regulate the breakdown of other proteins (proteolysis).  They can be classified as either "ubiquitin-dependent" or "ubiquitin-independent."
