7. Data demonstrate for the first time that the dentin sialoprotein (DSP) domain acts as a ligand in a Arg-Gly-Asp (RGD)-independent manner and is involved in intracellular signaling via interacting with integrin beta6.

15. mutations of the DSP-PP P4 to P4' cleavage site can block, impair or accelerate dentin sialoprotein phosphophoryn cleavage, and suggest that its Bone morphogenic protein 1 cleavage site is conserved in order to regulate its cleavage efficiency

16. DMP1 and DSPP were more abundant in carious than in sound samples.

17. Domain of dentine sialoprotein mediates proliferation and differentiation of human periodontal ligament stem cells.

18. analysis of a mutation in DSPP causing dentinogenesis imperfecta and characterization of the mutational effect

19. DSS domain of DPP functions as a novel cell-penetrating peptide, and these findings demonstrate new opportunities for intracellular delivery of therapeutic proteins and cell tracking in vivo.

20. efficiency of dentin sialoprotein-phosphophoryn processing is affected by mutations both flanking and distant from the cleavage site

Pig (Porcine) Dentin Sialophosphoprotein (DSPP) interaction partners

1. The porcine dentin sialophosphoprotein has an N-terminal domain with at least six N-glycosylations and a C-terminal domain with two glycosaminoglycan attachments and at least two O-glycosylations.

2. Astacins in the predentin matrix cleave Dspp.

3. isolation of DSP from pig dentin and demonstration that it is a proteoglycan

4. isolation and characterization of a third domain of DSPP, designated dentin glycoprotein (DGP)

5. correspondence between DSPP cleavage sites that occur in vivo and those generated in vitro demonstrates that MMP-2 and MMP-20 process DSPP into smaller subunits in the dentin matrix during odontogenesis

6. DPP length variations are polymorphic and are not associated with dentin defects

7. porcine DPP-derived arginyl-glycyl-aspartic acid peptide, but not its mutant arginyl-alanyl-aspartic acid peptide, significantly promoted cell migration

Mouse (Murine) Dentin Sialophosphoprotein (DSPP) interaction partners

1. our findings demonstrate that MMP9 is important for tooth development and DSP is a novel target of MMP9 during dentinogenesis.

2. The C-terminal DSP domain induced phosphorylation of occludin Ser(490) and focal adhesion kinase (FAK) Ser(722) and Tyr(576). Coexpression of DSP, occludin and FAK was detected in dental mesenchymal cells during tooth development. Occludin physically interacts with FAK, and occludin and FAK phosphorylation can be blocked by DSP and occludin antibodies.

3. stable Hey1overexpressing cells expressed higher levels of dentin sialophosphoprotein (DSPP) and exhibited higher mineralization capabilities following stimulation by differentiation medium. Furthermore, RNA interferencemediated knockdown of Hey1 downregulated the expression levels of DSPP in OLCs stimulated by differentiation medium.

4. Data demonstrate for the first time that the dentin sialoprotein (DSP) domain acts as a ligand in a Arg-Gly-Asp (RGD)-independent manner and is involved in intracellular signaling via interacting with integrin beta6. The DSP domain regulates DSPP expression and odontoblast homeostasis via a positive feedback loop.

5. Results show that transgenic expression of Dspp partially rescued the long bone defects of Dmp1-null mice and suggest that DSPP and DMP1 may function synergistically within the complex milieu of bone matrices.

6. Data show provide evidence that DSPP is important for normal mineralization of both dentin and enamel.

7. no significant dentin malformation was observed in Mep1b (-/-) or Mep1a (-/-) deficient mice.

8. overexpressing DPP inhibited skeletal development, suggesting that the balanced actions between the NH2- and COOH-terminal fragments of DSPP may be required for normal skeletal development.

9. Klf10 is involved in tooth development and promotes odontoblastic differentiation via the up-regulation of Dmp1 and Dspp transcription.

15. Data indicate that that Wnt10a regulates Dspp expression in mesenchymal cells.

16. Inactivation of DSPP leads to loss of alveolar bone and cementum in PDL of Dspp null mice. loss of DSPP results in periodontal diseases indicates that this molecule plays vital role in maintaining health of periodontium.
