Bone sialoprotein.
The search for a protein nucleator of hydroxyapatite crystal formation has been a focus for the isolation and characterization of the major non-collagenous proteins in bone. Of the proteins characterized to date, bone sialoprotein (BSP) has emerged as the only bona fide candidate for nucleation. BSP is a highly glycosylated and sulphated phosphoprotein that is found almost exclusively in minera...
متن کاملHuman Bone Sialoprotein
A cDNA encoding the human bone sialoprotein was isolated from a X Zap expression library (made from cultured human bone cell poly(A)+ RNA) using radiolabeled rat bone sialoprotein cDNA (Oldberg, A., and Heinegard, D. (1988) J. Biol. Chem. 263, 1943019432) as a probe. A 5’ 1-kilobase EcoRI fragment of the purified 3-kilobase clone was sequenced and found to contain the entire protein-encoding re...
متن کاملExpression of bone sialoprotein, a bone matrix protein, in human breast cancer.
Microcalcifications are often associated with human mammary lesions, particularly with breast carcinomas. To date, the molecular mechanism that leads to the deposition of hydroxyapatite in the mammary tissue has not been elucidated. Bone sialoprotein (BSP) is a glycoprotein the expression of which coincides with the appearance of the first hydroxyapatite crystals during bone development. In thi...
متن کاملTheoretical study of bone sialoprotein in bone biomineralization.
Bone sialoprotein (BSP) is an acidic, non-collagenous protein specific to bone proposed previously to promote hydroxyapatite (HAP) nucleation and modulate HAP nanocrystal growth. Specifically, two phosphorylated acidic amino acid sequences in BSP, highly conserved across several vertebrates, are the proposed active sites. We selected one of these sites, i.e. (Sp)(2)E(8), where Sp represents a p...
متن کاملThe role of bone sialoprotein in the tendon-bone insertion.
Tendons/ligaments insert into bone via a transitional structure, the enthesis, which is susceptible to injury and difficult to repair. Fibrocartilaginous entheses contain fibrocartilage in their transitional zone, part of which is mineralized. Mineral-associated proteins within this zone have not been adequately characterized. Members of the Small Integrin Binding Ligand N-linked Glycoprotein (...
