偷拍偷窥

Any introductory biochemistry student learns about mitochondrial proteins. We take it for granted that these protein assemblies must coexist in a super-complex. However, actually studying protein interactions in organelles remains challenging.

Fan Liu believes her cross-linking approach to analyzing mitochondria could be applied to describe the interactomes of other cellular organelles.

, a new faculty member and former postdoctoral fellow in lab at the in Berlin, is making this picture clearer by using cross-linking mass spectrometry to describe the interactome of intact mitochondria. Based on her work, she will be featured in a special session highlighting up-and-coming researchers hosted by the journal 偷拍偷窥 & Cellular Proteomics at the 偷拍偷窥 and 偷拍偷窥 Biology annual meeting.

Liu isn’t afraid of challenges. When she began as a postdoc, she learned computer programming and then for analyzing mass spectrometry cross-link data. She then applied the cross-linking approach to mitochondria to understand the organization and arrangement of protein complexes.

“I like the challenges of tackling technical difficulties,” she said. “It’s fascinating to think about how thousands of proteins are organized to large macromolecular assemblies.”

For Liu, this project is just the beginning. She thinks the next logical step is to use quantitative cross-linking mass spectrometry to understand how the mitochondrial interactome changes in different biological conditions. She also said this approach could be applied to other cellular organelles to describe their distinct interactomes.

This novelty and creativity are the reasons she finds research exciting.

“I like the freedom of thinking about interesting scientific questions,” she said. “I also enjoy inspiring discussion with colleagues and friends.”

Though she is dedicated to developing better analysis software and analytical procedures, Liu recognizes the importance of balance. She enjoys outdoor activities in her spare time.

“I like climbing in summer and skiing in winter,” she says. “It’s a good complement to sitting in front of the computer all day.”
