The enzyme 5-lipoxygenase (5-LO) initiates leukotriene biosynthesis from arachidonic acid. The 5-LO activating protein (FLAP) is crucial for efficient substrate utilization, with recent advances clarifying their roles.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Biology

Background:

  • Leukotriene biosynthesis is initiated by 5-lipoxygenase (5-LO) acting on arachidonic acid.
  • 5-LO activating protein (FLAP) is essential for efficient 5-LO activity in cells.
  • Significant advancements have been made in understanding 5-LO and FLAP over the past decade.

Purpose of the Study:

  • To review the molecular and cellular aspects of 5-lipoxygenase (5-LO) and FLAP.
  • To summarize recent progress in the expression, function, and regulation of these key proteins.
  • To provide an updated overview of leukotriene biosynthesis machinery.

Main Methods:

  • Literature review of molecular and cellular studies.
  • Analysis of research on protein expression and regulation.
