Osteocalcin (BGLAP) Antibody – Rabbit Polyclonal

This gene encodes a highly abundant bone protein secreted by osteoblasts that regulates bone remodeling and energy metabolism. The encoded protein contains a Gla (gamma carboxyglutamate) domain, which functions in binding to calcium and hydroxyapatite, the mineral component of bone. Serum osteocalcin levels may be negatively correlated with metabolic syndrome. Read-through transcription exists between this gene and the neighboring upstream gene, PMF1 (polyamine-modulated factor 1), but the encoded protein only shows sequence identity with the upstream gene product.

osteocalcin: Constitutes 1-2% of the total bone protein. It binds strongly to apatite and calcium. Belongs to the osteocalcin/matrix Gla protein family.
