About Jennifer Busch

Signal transduction is the means by which chemical signals, such as hormones, are released by the body and induce a chain reaction of subsequent protein activations that eventually cause certain physiological changes. Kinases are an important class of proteins within these transduction pathways. Specifically, I study cyclic-nucleotide dependent protein kinases. Cyclic AMP-dependent protein kinases (PKA) and cyclic GMP-dependent protein kinases (PKG) are important in many physiological processes such as blood pressure control, nerve function, and gastrointestinal motility. I am interested in learning more about the molecular mechanisms by which these kinases are regulated.

My personal interests include cycling, spending time outdoors, volunteering at my church, and reading historical fiction or biographical books. I also enjoy visiting new cities and towns; Nashville, TN, is my favorite so far.

Dr. Busch focuses on the molecular and biochemical regulation of cyclic nucleotide-dependent protein kinases, specifically cGMP-dependent protein kinases (PKG).  PKG plays important roles in a variety of physiological processes included blood flow and blood pressure modulation, learning and memory, and gastrointestinal motility.
