Laboratory of Structural Biology of Transcription Regulation
We use the means of integrative structural biology for detailed understanding of various biological processes. We focus on validation of biomolecular interactions that play important roles in human pathologies and can be exploited for therapeutic intervention. In a joint effort with medicinal chemists we develop small molecule inhibitors for these interactions. We study protein interaction networks that are implicated in regulation of gene transcription and also contribute to development of haematological malignancies. One of them is the iteractome of an epigenetic reader LEDGF/p75 that tethers other factors to the actively transcribed genes on chromatin. Its activity is essential for development of the two distinct diseases: HIV infection and Mixed-lineage leukemia (MLL).
