Identification of a Homeodomain Binding Element in the Bone Sialoprotein Gene Promoter That Is Required for Its Osteoblast-selective Expression
1 May 2000
Abstract excerpt
Bone sialoprotein is a 70-kDa extracellular matrix component that is intimately associated with biomineralization, yet the cis-acting elements of the Bsp gene that restrict its expression to mineralizing cells remain uncharacterized. To identify such elements, we analyzed a 2472-base pair fragment of the murine promoter that directs osteoblast-selective expression of a luciferase reporter gene and found that the...
