RT containing proteins.";
RL Biochem. Int. 15:271-277(1987).
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|PubMed:3501719}.
CC -!- SIMILARITY: Belongs to the osteocalcin/matrix Gla protein family.
CC {ECO:0000305}.
