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".
There are many different types of degrons, and they vary significantly even within these groups. However, they all play a role in regulating the speed at which proteins are broken down.  These mechanisms can be classified as either "ubiquitin-dependent" or "ubiquitin-independent."
