FLAP (Arachidonate 5-lipoxygenase-activating protein) is an integral membrane protein, which facilitates the transfer of the substrate arachidonic acid (AA) to 5-lipoxygenase (5-LO) to produce leukotrienes (LTs), and is shown to be indispensable for cellular LT biosynthesis. FLAP transfers arachidonic acid to 5-LOX protein, thereby enabling this enzyme to efficiently produce oxidized lipid products (mainly eicosanoids) that are important in cell growth, differentiation and death particularly apoptosis.

    FEN1-IN-1
    		Inhibitor 99.50%
    FEN1-IN-1 (compound 1) is a small molecule flap endonuclease 1 (FEN1) inhibitor with antitumor activity. FEN1-IN-1 binds to the active site of FEN1 and partly achieves inhibition by the co-ordination of Mg2+ ions. FEN1-IN-1 initiaties a DNA damage response and activates the ATM checkpoint signalling pathway, the phosphorylation of histone H2AX and the ubiquitination of FANCD2 in mammalian cells. FEN1-IN-1 is promising for research of cancers.
