Andrew Kruse

Professor - Biological Chemistry & Molecular Pharmacology Harvard Medical School

Dr. Kruse is a Professor of Biological Chemistry and Molecular Pharmacology at Harvard Medical School. His research focuses on the structure and function of transmembrane receptors, with an emphasis on using antibody fragments as tools to interrogate receptor function.

He began his independent career as an Assistant Professor at Harvard Medical School in 2014. Key research accomplishments include defining the structural basis for agonist action at the angiotensin II type 1 receptor and other GPCRs, cloning the sigma-2 receptor, and determining the first structure of a tetraspanin protein and showing how it regulates B cell activation. The Kruse lab developed a single-domain antibody fragment discovery platform that has now been distributed to more than 500 academic labs and has been licensed to four pharmaceutical companies. Dr. Kruse is a co-founder of two clinical-stage biotechnology companies: Tectonic Therapeutic and Seismic Therapeutic Inc., as well as the Institute for Protein Innovation, a non-profit research organization. He has received awards including the ASPET John J. Abel Award (2024), an Amgen Young Investigator Award (2019), an Alfred P. Sloan Research Fellowship (2017), a Vallee Scholars Award (2016), and an NIH Director’s Early Independence Award (2015). He received B.S. degrees in Mathematics and Biochemistry from the University of Minnesota in 2009, and completed a Ph.D. in Structural Biology at Stanford University in 2014, where he trained with Dr. Brian Kobilka.

Wednesday 29th April 2026
Activation of the RXFP1 Relaxin Receptor By Diverse Agonists
4:15 pm
  • RXFP1 is a GPCR involved in cardiovascular and renal adaptation to pregnancy
  • Using Cryo-EM, we determined the structure of this receptor bound to native relaxin hormone as well as the small molecule drug candidate AZD5462
  • The two ligands bind different surfaces on the receptor and induce divergent signaling outputs
