Our research focus is on the discovery of new biomolecular mechanisms from biological and medical data and the functional characterization of yet uncharacterized genes and pathways with theoretical/computational methods. Applications reach into medical data analysis, natural product, aging and rare diseases research. The starting point of our research are usually protein and genome sequences (typically coming from experimental of clinical collaborators) where other types of data (3D structures, expression profiles, phenotypes, medical data, etc.) can be mapped upon. Our success stories include the discovery of the SET domain methyltransferases (PMID: 10949293), ATGL (15550674), kleisins (12667442), many new protein domain functions and functional sequence patterns (for example in the GPI lipid anchor biosynthesis pathway such as the peptide synthetase activity of GPAA1 (24743167)).
In several cases, this research effort has involved the development of algorithms and software for biomolecular sequence, omics, clinical and other life science data analysis (see below). Examples are PTM and subcellular localization prediction tools for proteins (see 20221930, 20221930, 19029837, and 15575971), a sophisticated ANNOTATOR software suite for protein function discovery from sequence (27115649) or NSC, the highly cited protein surface computation algorithm (J. Comp. Chem. 16 pp. 273-284).
We discovered in 2018 that the productivity of academic life science research has drastically declined since 2000 if measured in terms of biomolecular mechanism and new gene function discovery: It is generally believed that full human genome sequencing was a watershed event in human history that boosted biomedical research, biomolecular mechanism discovery and life science applications. Yet, there is a persisting body of functionally insufficiently or completely not characterized genes (~10,000 protein-coding in the human genome) despite the availability of full genome sequences. A literature survey shows that the number of reported new protein functions had been steadily growing until 2000 but the trend reversed to a dramatic decline thereafter whereas, at the same time, the annual amount of new life science publications doubled between 2000 and 2017.
Below, we list some recent publications in A) gene function discovery studies, B) about protein functions in the GPI lipid anchor pathway, C) discovery of gene functions and new compounds in natural product research and in aging, D) about bioethics research and science history and E) methods development: Towards a unified sequence homology theory, disordered protein regions and OMICS data algorithms
