Abstract excerpt
The human salivary proline-rich proteins (PRPs) are coded by six closely linked genes on chromosome 12p13.2. Two of the PRP genes, PRH1 and PRH2, code for acidic PRPs that are functionally important in binding to teeth surfaces, in maintaining a supersaturated concentration of salivary calcium, and in promoting adherence of potentially pathogenic oral bacteria to the teeth surfaces. A frequent acidic PRP...
