Interestingly, there is a report on the identification of tannin-binding proteins in the saliva of Papio hamadryas (sacred baboon) (12). The tannin-binding proteins identified were serum albumin. Proline-rich proteins, histatins, and statherins are supposed to be the most reactive salivary proteins. This study aims to contribute to the knowledge of the tannin–protein binding process in saliva. It was identified for the first time in several soluble tannin–human salivary protein by: Proline-rich proteins (PRPs) in saliva have been shown to provide protection against tannin, but little is known about the mechanism of protection and interaction of other salivary proteins with by:   Howler monkeys produced slightly alkaline saliva that may aid in the binding interaction between tannin and salivary proteins. We used gel electrophoresis to describe the salivary protein profile and this analysis along with a tannin‐binding assay allowed us to detect several TBSPs in .

Tannin-binding salivary proteins (TBSP) are considered to be counter-defences acquired in the course of evolution by animals whose natural forage contains such tannins. As tannins mostly occur in browse material but not in grasses, it is assumed that grazers do not have a need for TBSP.   The determination of salivary biomarkers as a means of monitoring general health and for the early diagnosis of disease is of increasing interest in clinical research. Based on the linkage between salivary proteins and systemic diseases, the aim of this work was the identification of saliva proteins using proteomics. However, there are other proteins in the saliva of mammalian herbivores that also have a high tannin-binding affinity, which may allow for tolerance of low-quality food resources. Domestic goats (Capra hircus) are able to survive on low quality, tannin-rich food : Melissa H. Schmitt, Melissa H. Schmitt, David Ward, David Ward, Adrian M. Shrader, Adrian M. Shrader. The tannin-binding protein from deer saliva is a small glycoprotein containing large amounts of proline, glycine, and glutamate/glutamine. The protein is not closely related to the proline-rich salivary proteins found in rats and other nonruminant mammals.

Tannin­Binding Proteins Detected by Electrophoresis on Native Gels This method allows detection of proteins in saliva or other samples which selectively bind to tannins. Either precipitable or nonprecipitable complexes can be detected with this method, as with gel shift Tannin-Binding Proteins Detected by Electrophoresis on Native Gels. Tannin-binding salivary proteins in three captive rhinoceros species Division of Zoo Animals and Exotic Pets. To evaluate the amount and type of condensed tannins binding salivary proteins, which are supposed to be involved in astringent sensation, model systems allowing further analyses of proteins and condensed tannins were developed. The precipitates formed after addition of grape seed tannins to salivary proteins indicate that a binding interaction occurs. Dissociation of insoluble complexes was. Tannins are characterized by protein-binding affinity. They have astringent/bitter properties that act as deterrents, affecting diet selection. Two groups of salivary proteins, proline-rich proteins and histatins, are effective precipitators of tannin, decreasing levels of available tannins. The possibility of other salivary proteins having a co-adjuvant role on host defense mechanisms against.
