An L1 element disrupts human bone sialoprotein promoter: lack of tissue-specific regulation by distalless5 (Dlx5) and runt homeodomain protein2 (Runx2)/core binding factor a1 (Cbfa1) elements.

Abstract excerpt

Bone sialoprotein (BSP) is a phosphorylated and sulphated glycoprotein with hydroxyapatite nucleating properties that is specifically expressed in association with physiological and pathological mineralization. Although previous studies have indicated that tissue-specific expression of murine BSP is regulated through a proximal homeodomain element that binds distalless5 (Dlx5) transcription analysis of the...
