Unraveling aquaporin interaction partners

Scrutinizing ciliopathies by unraveling ciliary interaction networks.

Research of cilia has gained significant momentum in the last 15 years, as an increasing number of human genetic diseases were found to be caused by disruption of a protein that localizes to cilia. These ciliopathies are as diverse as the functions of the associated proteins, covering a spectrum of overlapping phenotypes that ranges from relatively mild characteristics in isolated tissues with ...

Systematic Identification of Oncogenic EGFR Interaction Partners

The epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase (TK) that-once activated upon ligand binding-leads to receptor dimerization, recruitment of protein complexes, and activation of multiple signaling cascades. The EGFR is frequently overexpressed or mutated in various cancers leading to aberrant signaling and tumor growth. Hence, identification of interaction partners that...

Proteomics Analysis Reveals Novel RASSF2 Interaction Partners

RASSF2 is a tumor suppressor that shares homology with other Ras-association domain (RASSF) family members. It is a powerful pro-apoptotic K-Ras effector that is frequently inactivated in many human tumors. The exact mechanism by which RASSF2 functions is not clearly defined, but it likely acts as a scaffolding protein, modulating the activity of other pro-apoptotic effectors, thereby regulatin...

Inferring interaction partners from protein sequences.

Specific protein-protein interactions are crucial in the cell, both to ensure the formation and stability of multiprotein complexes and to enable signal transduction in various pathways. Functional interactions between proteins result in coevolution between the interaction partners, causing their sequences to be correlated. Here we exploit these correlations to accurately identify, from sequenc...
