Area of Science:

  • Biochemistry
  • Cell Biology
  • Molecular Medicine

Background:

  • Cellular signaling relies on lipids from phospholipid and phosphoinositide metabolism.
  • This metabolism involves key enzymatic processes: hydrolysis by phospholipases and phosphatases, and phosphorylation by kinases.
  • Dysregulation of these enzymes is linked to various pathologies, presenting therapeutic opportunities.

Purpose of the Study:

  • To introduce novel reagents for studying lipid metabolism.
  • To enable monitoring of enzyme activity and intracellular lipid dynamics.
  • To facilitate the identification of lipid-protein interactions.

Main Methods:

  • Development of three reagent categories at the University of Utah and Echelon Biosciences.
  • Utilizing these reagents for in vitro enzyme activity assays.
