RT "Teleost fish osteocalcin 1 and 2 share the ability to bind the calcium
RT mineral phase.";
RL Fish Physiol. Biochem. 40:731-738(2014).
CC -!- FUNCTION: Binds strongly to apatite and calcium. {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
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}.
CC -!- SIMILARITY: Belongs to the osteocalcin/matrix Gla protein family.
CC {ECO:0000305}.
