    text
  • abundant PLOD3 localising to the basement membrane in normal skin
    • basic FUNCTION
  • catalyzing the hydroxylation of lysyl residues in collagenous sequences
  • multifunctional enzyme capable of catalyzing hydroxylation of lysyl residues and O-glycosylation of hydroxylysyl residues producing either monosaccharide (Gal) or disaccharide (Glc-Gal) derivatives
  • collagen galactosyltransferase activity (Risteli 2009)
  • is the multifunctional collagen-modifying enzyme possessing LH, hydroxylysine galactosyltransferase (GT), and galactosylhydroxylysine-glucosyltransferase (GGT) activities
  • major function of PLOD3 in osteoblasts is to glucosylate galactosylhydroxylysine residues in type I collagen and impairment of this PLOD3 function significantly affects type I collagen fibrillogenesis
  • PLOD3 is an important regulator of adiponectin biosynthesis, secretion and activity
  • modulates cancer progression and metastasis
    • CELLULAR PROCESS protein, post translation

    PATHWAY
    metabolism
    signaling
    a component
  • FKBP10 forms complexes with PLOD2 splice variants LH2A and LH2B but not with PLOD1 and PLOD3
    • INTERACTION
    DNA
    RNA
    small molecule metal binding,
  • iron Fe2+
  • ascorbate
    • protein
  • modifies the lysine residues in the collagenous domain of adiponectin, which has important roles in glucose and lipid metabolism and inflammation
  • recruitment of MMP9 to the fibroblast cell surface occurs through its fibronectin-like (FN) domain and the molecule responsible for the recruitment is PLOD3
  • VIPAS39, with its partner proteins, regulate sorting of PLOD3 into newly identified post-Golgi collagen IV carriers and VIPAS39-dependent sorting is essential for modification of lysines in multiple collagen types
    • cell & other
    REGULATION
    Other regulation of post-Golgi PLOD3 trafficking is essential for collagen homeostasis and for the development and function of multiple organs and tissues
