Protein Design <strong>and</strong> Evolution Laboratory<br />

Dr. Vikas N<strong>and</strong>a joined CABM in September of 2005 after studying as an<br />

NIH National Research Service Award postdoctoral fellow in the laboratory<br />

of Dr. William DeGrado at the Department of Biochemistry <strong>and</strong> Biophysics<br />

at the University of Pennsylvania School of Medicine. His research focused<br />

on studying the molecular basis of transmembrane interactions among<br />

integrins involved in regulation of platelet hemostasis. Prior to that, Dr.<br />

N<strong>and</strong>a received his doctorate in Biochemistry from Johns Hopkins<br />

University. His laboratory is supported by federal grants including a recent<br />

highly competitive NIH New Innovator Award.<br />

.<br />

Our group is interested in constructing new proteins <strong>for</strong> applications in biomedical<br />

research, nanotechnology <strong>and</strong> as tools <strong>for</strong> underst<strong>and</strong>ing how proteins fold <strong>and</strong><br />

evolve. Significant progress has been made in the last decade using sophisticated<br />

computer programs to design proteins with novel folds <strong>and</strong> functions. We maintain<br />

<strong>and</strong> develop the software package, protCAD (protein computer aided molecular<br />

design), which has been applied to protein design, structure prediction <strong>and</strong> docking<br />

of protein lig<strong>and</strong> complexes.<br />

Computational Design of an Extracellular Matrix<br />

The extracellular matrix (ECM) is a complex network of collagens, laminins,<br />

fibronectins <strong>and</strong> proteoglycans that provides a surface upon which cells can adhere,<br />

differentiate <strong>and</strong> proliferate. Defects in the ECM are the underlying cause of a wide<br />

spectrum of diseases. The ECM mediates endothelial cell polarity <strong>and</strong> under normal<br />

conditions can suppress pre-oncogenic transitions to a neoplastic state. We are<br />

constructing artificial, de novo collagen-based matrices using a hierarchic<br />

computational approach. These matrices will be physically characterized in the<br />

laboratory <strong>and</strong> used to probe the role of chemical <strong>and</strong> spatial organization in the<br />

ECM on the tumor <strong>for</strong>ming potential of adhered cells. Successfully designed<br />

matrices will be applied to engineering safer artificial tissues.<br />

Rational Design of Enhanced Peptide Therapeutics<br />

Peptides are an emergent <strong>and</strong> important class of therapeutics with over <strong>for</strong>ty<br />

compounds on the market <strong>and</strong> nearly 700 more in clinical or pre-clinical trials.<br />

During the development of peptide drugs, D-enantiomers of amino acids are<br />

frequently incorporated to improve pharmacokinetic <strong>and</strong> pharmacodynamics<br />
