Ub is found throughout an entire cell and can exist in a free state or combined with other protein. If it is combined with other protein then it is attached by a covalent bond between the glycine and lysine on the proteins. Ub has a role to play in many cell processes. For example – during the G1 phase of mitosis Ub is conjugated to the protein cyclin and hence play an important role in controlling the cell cycle. Ub conjugation is also present in DNA repair, the regulation of transcription, apoptosis and embryogenesis.
