Congratulations to Dr. Jeff Ranish on his promotion to Associate Professor. Jeff has been with ISB since its founding in 2000. Read about the Ranish lab group.
Our work describing a new crosslinking mass spectrometry technology for studying conformational and structural changes in proteins and proteins complexes has been published in eLife.
Jie Luo and Jeff Ranish collaborated on a project to determine the molecular architecture of the NuA4/Tip60 co-activator complex. This protein complex functions to allow proper control of gene expression and DNA repair by allowing other proteins to access the DNA in the cell nucleus. The new information about the structure and function of TIP60 could provide insight into different diseases where the protein complex plays a role, such as Alzheimer’s and various cancers. The work was published in Science.
Dynamic conformational and structural changes in proteins and protein complexes play a central and ubiquitous role in the regulation of protein function, yet it is very challenging to study these changes, especially for large protein complexes, under physiological conditions. To address this challenge, we created a novel isobaric crosslinker, Qlinker, for studying conformational and structural changes in proteins and protein complexes using quantitative crosslinking mass spectrometry (qCLMS).
