Linear Ubiquitination Quantitative Mass Spectrometry

Linear ubiquitination is an important protein modification in organisms, playing a crucial role in regulating various biological processes, including immune responses, inflammatory responses, cell signal transduction, and DNA damage repair. However, due to its specificity and complexity, research on linear ubiquitination has faced technical challenges in the past. Fortunately, recent technological advancements have enabled us to study linear ubiquitination in greater depth, with quantitative mass spectrometry being one of the most significant breakthroughs.

 

Linear Ubiquitination

Linear ubiquitination is a special type of protein modification, which involves attaching ubiquitin proteins to target proteins in a linear manner. This type of modification can significantly alter the activity, stability, and subcellular localization of target proteins, thus affecting their function in biological processes.
