Software Solutions for Deep Mutational Scanning & Selection - Medical / Health Care
Cyrus’s protein biochemistry capabilities include advanced selection methodologies in both yeast and mammalian cell systems. These tools can interrogate large numbers of mutations in cell surface receptors and many globular proteins, offering a unique path forward for protein optimization based on high quality, physiologically-relevant data in eukaryotic or – specifically – human cells.
Explore Mutational Landscape
Exhaustive single point mutations of ACE2 were tested by yeast display to identify mutations that affect binding to SARS-CoV-2’s Spike protein. By sequencing the mutations that retained binding, we can explore sequence diversity. Deep mutational scans identified conserved positions (in blue) that are critical for binding. Positions with high mutation tolerance (in yellow) are under selection to change. From “Narayanan KK, Procko E. Deep Mutational Scanning of Viral Glycoproteins and Their Host Receptors.
