Biological function summary

The protein influences immune defense in salivary secretions. PSP is part of salivary innate immune responses and works alongside other salivary proteins for maintaining oral health. This protein contributes to the barrier function against bacteria and viruses inside the mouth. PSP is capable of agglutination of microbes making their removal by saliva more efficient.

Pathways

PSP is extensively involved in the immune defense pathways of the oral cavity and initial gastrointestinal tract. In these pathways PSP functions within networks including proteins such as mucins and histatins which collectively contribute to oral homeostasis and microbial balance. PSP’s ability to bind bacteria supports its role in these pathways by enhancing the prevention of infection and inflammation.
