Z03 - Proteomics platform for protein interaction mapping
The focus of Z03 is on supporting the CRC958 with proteomic approaches to delineate interaction partners of membrane scaffolds, to determine post‐translational modifications (PTM) or to profile the intactness and stoichiometry of purified complexes for structural investigations. Typical shotgun proteomic experiments were used in collaboration with projects A03, A13, A19, A21 and A22, with the 18O/16O method becoming a standard procedure to perform quantitative experiments of primary cells or tissue samples. Phosphorylation of Bruchpilot by SRPK79D kinase was investigated in conjunction with A06 (Wahl, Sigrist).
Furthermore, we apply native MS (Figure 1) - where non-denaturing buffers are used in order to preserve the native protein conformation - to investigate protein complexes in their intact form or to analyze complex topologies by tandem MS experiments in which individual protein subunits are released from a larger complex by collision-induced dissociation (CID). In collaboration with A07, native mass spectrometry was utilized to evaluate a possible dimerization of the SH3A domain of intersectin.

Moreover, we use cross-linking MS experiments for interactomic profiling. For instance, by examining neuronal synapses purified from mouse brain or Drosophila heads, we have obtained comprehensive interaction networks in both biological systems. As an illustrative example (Figure 2), we were able to obtain protein interactions together with their binding interfaces of many major proteins/complexes at the synapse. A clear picture emerges from the aggregated dataset: proteins that are known to be localized to synaptic membranes, synaptic vesicles, postsynaptic densities and mitochondria are strongly clustered - a result that is well in agreement with the known spatial organization of these proteins at synapses based on ultra-structural and high-resolution microscopy data.
