OMass Technologies Announces Publication Demonstrating the Impact of Lipid interactions on GPCR Signalling in Nature

July 11, 2018

Oxford, 11 July 2018 – OMass Technologies (“OMass”), a biotechnology company using structural mass spectrometry to drive drug discovery, today announced the publication of an article in Nature describing the involvement of lipid molecules in G-protein-coupled receptors (GPCR signalling). The study was led by Dr Hsin-Yung Yen, CSO of OMass Technologies and performed in collaboration with Prof. Dame Carol Robinson’s research group at the University of Oxford.

Dr Hsin-Yung Yen and his co-authors* describe how interactions between GPCRs and G-proteins, which are involved in many physiological processes and are key drug targets, are highly regulated by interactions with specific lipid molecules. Although high-resolution structural information is emerging for GPCRs, the effects of lipids on the receptor’s function are largely unknown. Native mass spectrometry was used to resolve discrete populations of endogenous GPCR-lipid species to understanding their effects on down-stream signalling.

The full manuscript “PtdIns(4,5)P2 stabilizes active states of GPCRs and enhances selectivity of G-protein coupling” can be found in the July 2018 issue of Nature –

OMass specialises in applying state-of-the-art mass spectrometry platforms to characterising intact protein assemblies. By providing both access to technology and expertise through collaborations with world-leading pharmaceutical companies, the company is focussed on studying some of the most challenging protein targets in drug discovery.
