What is "osteocalcin"

n. (context biology English) A protein found in bone and dentin, manufactured by osteoblasts. It plays a role in mineralization and calcium ion homeostasis.

Osteocalcin, also known as bone gamma-carboxyglutamic acid-containing protein (BGLAP), is a noncollagenous protein found in bone and dentin. Because it has gla domains, its synthesis is vitamin K dependent. In humans, the osteocalcin is encoded by the BGLAP gene. Its receptor is GPRC6A.
