Protein cross-linking of macromolecular complexes (A10)

• Subject Area: Biochemistry
• Term: from 2010 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 105286809

We will perform protein cross-linking combined with mass spectrometry (MS) of resting and stimulated B cells. The cross-linked interactome of key signaling molecules will be related to the phosphorylation states of the B cells upon B cell receptor (BCR) stimulation and information on how phosphorylation influences molecular interactions will be obtained. Further, we will establish protein-DNA cross-linking combined with MS of in vitro reconstituted protein-DNA complexes and in in vivo and ex vivo systems using UV-light and chemical cross-linker. Structural function relationships in DNA–protein systems like chromatin will be obtained.
