Irina Pogozheva has experience in theoretical and experimental research of membrane proteins including ESR and other spectroscopic studies of rhodopsin, development and application of an ESR-based method for in situ measurement of NO release, application of computational methods for modeling of protein structure, conformational transitions, and protein-membrane interactions. She is co-author of 50 papers published in peer-reviewed journals, 16 meeting abstracts, and two book chapters.
Based on the experimental and computationally-derived restraints, she modeled diverse membrane proteins, including various G-protein coupled receptors (opioid, melanocortin, adrenergic, neurokinin, gonadotropin-releasing hormone, and glycoprotein hormone receptors), ABC-transporters (TAP1/TAP2), single-helical membrane proteins (cytochrome P450/cytochrome b5, cytochrome P450/cytochrome P450 reductase) and membrane-active peptides (colicin toxins, antimicrobial peptides). Models of opioid receptors were successfully used for structure-based design of opioid peptides with desired pharmacological profiles.
She also participated in design and development of databases for membrane proteins, including the OPM (Orientations of Proteins in Membranes) database, a resource that provides comprehensive information about proteins with known three-dimensional structures and their predicted orientations with respect to the lipid bilayer, and the Membranome database that provides models of transmembrane domains of single-helical membrane proteins.
