Official Full Name: bone gamma-carboxyglutamate protein
Also known as: OC; BGP; OCN
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 carboxyglutamic acid) domain that functions to bind calcium and hydroxyapatite, the mineral component of bone. Serum osteocalcin levels may be inversely correlated with metabolic syndrome. There is a read-through transcription between this gene and the adjacent upstream gene PMF1 (polyamine regulatory factor 1), but the encoded protein is only consistent with the upstream gene product sequence.
