Localization of osteocalcin (BGP) during fish (Sparus aurata) development by in...
Descrição
Osteocalcin (Bone Gla protein, BGP) is a small noncollagenous protein which is synthesized by osteoblasts and odontoblasts and is found exlusively in mineralized bony tissues. Although isolated for the first time in 1978, only recently has a function for this protein been suggested, specifically in controlling hydroxyapatite crystal growth. Appearance of osteocalcin could be linked to the presence of an hydroxyapatite-containing bony skeleton, since the protein was never found in cartilaginous fishes. Furthermore, within its primary sequence the amino acid residues known to be essential for its function are present in fish as well as in mammals, suggesting that function has been conserved over 400 million years of evolution. Taken totgether, these findings prompted us to study in detail the localization of osteocalcin gene expression in fish.
