RA Carstanjen B., Wattiez R., Amory H., Lepage O.M., Remy B.;
RT "Isolation and characterization of equine osteocalcin.";
RL Ann. Med. Vet. 146:31-38(2002).
CC -!- FUNCTION: Constitutes 1-2% of the total bone protein. It binds strongly
CC to apatite and calcium.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- PTM: Gamma-carboxyglutamate residues are formed by vitamin K dependent
CC carboxylation. These residues are essential for the binding of calcium.
CC {ECO:0000255|PROSITE-ProRule:PRU00463, ECO:0000269|Ref.1}.
CC -!- SIMILARITY: Belongs to the osteocalcin/matrix Gla protein family.
CC {ECO:0000305}.
