Supplementary information

The proteins PRH1 and PRH2 also known as proline-rich proteins play important roles in the oral cavity. They have a significant presence in human saliva where they are involved in forming acquired enamel pellicle. PRH1 and PRH2 are secretory proteins with molecular masses of approximately 30 kDa. Their expression primarily occurs in the salivary glands and they are abundant in saliva contributing to the oral microenvironment's protective qualities. These proteins are encoded by closely related genes often found within the same multigene complex which increases genetic variability and adaptability of their functions.

Biological function summary

PRH1 and PRH2 contribute to several protective processes in the mouth. They interact with bacteria modulating microbial colonization. The proteins also bind to calcium and phosphate ions which help maintain dental enamel integrity. Part of the proline-rich protein family they work together as a complex to help stabilize the enamel surface and prevent tooth decay. These proteins possess binding capabilities that enable them to interact effectively with other molecules increasing their functional versatility.

Pathways

PRH1 and PRH2 engage in dental enamel formation and bacterial adhesion pathways. These proteins interact with members of the salivary protein complex to initiate and maintain enamel calcification. Through these interactions they influence pathways like the oral defense mechanism pathway working with related proteins such as statherin that also play roles in maintaining tooth integrity and oral hygiene. This relationship is important in binding to bacteria and controlling biofilm development on teeth surfaces.

PRH1 and PRH2 association to dental health conditions such as dental caries and periodontal disease is significant. These proteins' dysregulation can lead to increased susceptibility to cavities and gingival issues. Carious lesions show altered expression of these salivary proteins indicating their protective significance. Associations with proteins like amelogenin and enamelin which contribute to tooth structure highlight their importance in preserving tooth health and preventing disease. Uncovering their variations offers insights into individual risks for dental disorders.
