CVI Program Unit(s):
Cardiovascular Development / Congenital Heart Disease
Myocyte Biology / Heart Failure
Thrombosis / Hemostasis
Pulmonary

CVI Research Description:
We are working on the role of a poorly understood posttranslational modification -- arginylation -- in cardiovascular development. Arginylation is mediated by arginyltransferase Ate1. Its knockout leads to embryonic lethality in mice and severe cardiovascular defects. My lab is focused on uncovering the underlying mechanisms of these defects on the molecular, cellular, and organizmal levels.
