Secondry Information

Protein Function proteoglycan known to impact mammary cell proliferation in humans and rodents; regulate fibrillogenesis; positively or negatively affect cell proliferation
Biochemical Properties C-terminal region of decorin is cysteine-rich, the central region is made of twelve leucine-rich repeats and is generally recognized as a ligand-binding domain (discussed in further detail below), and the N-terminal region contains the single a single chondroitin/dermatan sulfate side chain and a distinct pattern of cystine residues
Significance in milk ECM proteoglycan known to impact mammary cell proliferation in humans and rodents
PTMs covalent linkage of GAG chains; specifically, the addition of a single chondroitin or dermatan sulfate side chain on a serine residue on the N-terminal side of decorin
Site(s) of PTM(s)
