Philip B. Wedegaertner

Philip B. Wedegaertner is a Professor in the Department of Biochemistry & Molecular Biology at the College of Life Sciences, Thomas Jefferson University, and serves as Co-Director of the Biochemistry, Structural, & Molecular Biology PhD Program.

His educational background includes a PhD in Biochemistry from the University of California, San Diego (1991).

Dr. Wedegaertner's research program centers on G protein signaling mechanisms. Specifically, his laboratory investigates:

• The reversible membrane targeting of G protein alpha and beta-gamma subunits, including pathways for plasma membrane localization, subunit assembly, and GPCR-activated translocation
• The role of Rho guanine-nucleotide exchange factors (RhoGEFs) in linking heterotrimeric G proteins to Rho GTPase signaling, with focus on cytoskeletal regulation and mitosis
• The membrane targeting and nucleocytoplasmic shuttling of G protein-coupled receptor kinases (GRKs), particularly the novel amphipathic helix and palmitoylation in GRK6

Analysis of his recent publications reveals a strong emphasis on GPCR signaling dysregulation in cancer, membrane trafficking mechanisms, and therapeutic targeting of G protein pathways. His work bridges biochemical, cell biological, and pharmacological approaches to address fundamental questions in signal transduction.
