Domain structure and sequence distribution in dentin phosphophoryn.
Phosphophoryn (PP) is a protein unique to the mineralized matrix of dentin. It also has a unique composition, with aspartic acid and phosphoserine comprising greater than 85% of all amino acid residues. Because of this unique composition and high content of phosphoserine, it has been difficult to apply direct peptide sequencing procedures effectively. However, to understand its function, and to...
متن کاملThe distribution of aspartic acid residues in bovine dentine phosphoprotein.
Recently, Weiner and Hood (Science 190:987989, 1975) reported the use of an acid hydrolysis procedure in the study of the aspartic acid linkages of the soluble protein of the organic matrix of mollusk shells. Peptide bonds on both sides of aspartic acid residues have been shown to be particularly labile to hydrolysis by dilute acetic or hydrochloric acids (SCHULTZ et al, Biochemistry 1:694-698,...
متن کاملDentin phosphophoryn promotes cellular migration of human dental pulp cells.
Dentin phosphophoryn (DPP) is a dentin sialophosphoprotein gene product that has an RGD motif and repeat sequences of aspartic acid and phosphoserine. To date, the function of DPP in the early stage of reparative dentin formation still remains unclear. The objective of this study was to evaluate the effects of DPP on pulp cell migration and proliferation. DPP promoted cell migration in a concen...
متن کاملInduction of Reparative Dentin Formation on Exposed Dental Pulp by Dentin Phosphophoryn/Collagen Composite
The ultimate goal of vital pulp therapy is to regenerate rapidly dentin possessing an excellent quality using a biocompatible, bioactive agent. Dentin phosphophoryn (DPP), the most abundant noncollagenous polyanionic protein in dentin, cross-linked to atelocollagen fibrils was applied to direct pulp capping in rats. After 1, 2, and 3 weeks, the teeth applied were examined on the induction of re...
متن کاملLocalization of D- -Aspartic Acid–Containing Proteins in Human Eyes
PURPOSE. Biologically uncommon D-aspartic acid (D-Asp) has been detected in proteins from various human tissues in elderly donors. Previous studies have identified D-Asp residues at four different specific sites in -crystallin from aged human lenses and an increased amount of D-Asp residues with age. D-Asp is formed as a result of racemization and accumulates with age; therefore, it is thought ...
