Ubiquitin is an intracellular signalling molecule that is conjugated to various proteins. Ubiquitin conjugation to itself yields Lys- or Met-conjugated chains, thus expanding its repertoire of ...

Figure 1: Discovery of the ligation of ubiquitin to lysozyme, a substrate of the proteolytic system. As indicated before 19, the main lesson from our story is the continued importance of the use ...

A new study has identified an enzyme that plays an important role in breaking down unneeded or damaged proteins in the heart – an important process for maintaining heart health.

Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases ...

A disrupted protein degradation process in heart muscle cells can lead to a range of severe heart diseases. In the case of ...

An enzyme called Ubiquitin-specific peptidase 5 is a key factor in protein quality in heart muscle cellsA disrupted protein ...

Most of our prior work focused on the Ubl protein SUMO as it is essential in budding yeast and its conjugation to substrates requires an enzyme cascade that involves fewer factors in comparison to the ...

C-terminal amidation is a PTM that involves the addition of an amid group to the C-terminus of a peptide or protein. Currently there is no direct evidence to suggest that C-terminal amidation of ...
