PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • three canonical residues of the catalytic triad with a nucleophile component including asparagine instead of serine
  • an acid motif and an histidine at residue 327
  • an alpha /beta-hydrolase domain-containing hydrolase/acyltransferase/esterase/lipase and phospholipase motifs
  • secondary structure alpha/beta hydrolase fold
    HOMOLOGY
    interspecies ortholog to C.elegans gene CGI-58
    homolog to yeast Ict1p
    intraspecies paralog to FLJ1286
    Homologene
    FAMILY
  • peptidase S33 family
  • ABHD4/ABHD5 subfamily
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm
    basic FUNCTION
  • involved in cholesterol biosynthesis
  • promotes the catabolism of stored fat in adipose and non-adipose tissues, by co-activating the adipose triglyceride lipase (PNPLA2), which hydrolyzes triacylglycerol to yield diacylglycerol and fatty acid
  • acting as an acyltransferase, mediating acylation of lysophosphatidic acid
  • ABHD5, a protein activator of PNPLA2, coordinates with PLIN1 in controlling basal and stimulated lipolysis
  • DGAT1 is involved in the synthesis of triacylglycerol where as ABHD5 is a hydrolase and participates in the fatty acid oxidation process, yet inhibition of both enzymes similarly promotes prostate cancer cell death

    INTERACTION

    small molecule
    protein
  • interaction of ABHD5 and PLIN5 occurs mainly, if not exclusively, on the surface of lipid droplets, and is essential for regulating the activity of PNPLA2 at lipid droplets containing PLIN5

    Marker
  • ABHD5, PGRMC1 and FDFT1 are novel markers for sebaceous carcinoma and can reliably distinguish sebaceous neoplasms from non-sebaceous tumors, specifically basal cell carcinoma (BCC) with clear cell features
