Transverse tubules (T-tubules) play a significant role in muscle contraction. However, the underlying mechanism of their ...

When proteins within the body get tagged with a molecule called ubiquitin, they are essentially marked for destruction. But they can be saved; a deubiquitinase enzyme can remove the ubiquitin, keeping ...

Cells must continually adjust their protein composition, which includes protein synthesis as well as degradation. Most ...

Ubiquitin is a small protein consisting of 76 amino acids that binds to lysine residues of substrates, usually by a combination of three enzymes: a ubiquitin-activating enzyme (E1, two types), a ...
