  • 'GDXG' lipolytic enzyme family
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     plasma membrane
  • translocation to the lipid droplet occurs by virtue of PLIN1 localization to the surface of lipid droplets and a physical interaction of LIPE occurring with sequences within the N-terminal region of PLIN1
  • basic FUNCTION
  • hydrolyzing stored triglycerides to free fatty acids
  • esterase and lipase, which are essential for spermatogenesis
  • playing an important role in regulating catecholamine-induced lipolysis
  • one of the mechanisms by which LIPE modulates adipose metabolism is potentially by providing intrinsic ligands or pro-ligands for PPARG
  • in adipose tissue, plays an important role in catecholamine-stimulated hydrolysis of stored lipids, thus mobilizing fatty acids
  • importance of LIPE for normal lipid metabolism in response to a high fat diet
  • triacylglycerol hydrolase and cholesterol esterase that is essential for male fertility
    metabolism lipid/lipoprotein
    a component
  • activated, phosphorylated LIPE translocates to the surface of the lipid droplet and forms a complex with multiple proteins facilitating efficient lipid hydrolysis
    small molecule
  • interacting with FABP4
  • physical interaction of LIPE with PLIN1 (can interact with an N-terminal region located between AAs 141 and 200 of PLIN1 as well as with a C-terminal region located between AAs 406 and 480)
  • NR1H3 binds to the proximal regions of the PLIN1 and LIPE promoters
  • transcription of LIPE is regulated by the PPARG/MRAP-mediated signaling pathway

    constitutional     --other  
    altered PNPLA2 and LIPE expression in skeletal muscle could promote diacylglycerol accumulation and disrupt insulin signaling and action
    constitutional     --over  
    LIPE or PNPLA2 overexpression resulted in increased triglyceride-specific hydrolase capacity, but only PNPLA2 overexpression increased whole cell lipolysis
  • to obesity and non insulin dependent diabetes
  • to male infertility
  • Variant & Polymorphism other
  • variants might be associated with a physiological effect on beta-adrenoceptor-mediated fat oxidation, at least in overweight-obese female subjects
  • genetic variation of LIPE may be a risk factor for male infertility
  • Candidate gene
    Therapy target
    pharmacological inhibition of lipases LIPE and PNPLA2) may represent a powerful strategy to avoid the devastating condition of cachexia in response to cancer or other chronic diseases
