Conserved Site

FLAP/GST2/LTC4S, conserved site (IPR018295)

Short name: FLAP/GST2/LTC4S_CS


These are proteins of 150 to 160 residues that contain three transmembrane segments. As a signature for these proteins a conserved region between the first and second transmembrane domains has been used.

This entry contains the following mammalian proteins, which are evolutionary related [PMID: 8703034]:

  • Leukotriene C4 synthase (EC: (gene LTC4S), an enzyme that catalyzes the production of LTC4 from LTA4.
  • Microsomal glutathione S-transferase II (EC: (GST-II) (gene GST2), an enzyme that can also produces LTC4 fron LTA4.
  • 5-lipoxygenase activating protein (gene FLAP), a protein that seems to be required for the activation of 5-lipoxygenase.
