A method has been developed for detecting tannin-binding proteins in the saliva of herbivores. The method is simple and requires only small quantities of crude saliva. The saliva of deer, a browsing ruminant, has been compared to that of domestic sheep and cow, which are grazing ruminants. The browser, which normally ingests dietary tannin, produces tannin-binding proteins, while the grazers do not produce such proteins. The tannin-binding protein from deer saliva is a small glycoprotein… 
Salivary tannin-binding proteins: A foraging advantage for goats?
Abstract Tannins are a key chemical defense that plants use against mammalian herbivores. To cope with tannins, many herbivores have evolved salivary tannin-binding proteins that precipitate tannins
No Major Role for Binding by Salivary Proteins as a Defense Against Dietary Tannins in Mediterranean Goats
TLDR
There is not a major role for salivary tannin-binding proteins in goats, and different tendencies of goat breeds to consume tann in-rich browse does not appear to be related to differences in salivARY tannIn- binding proteins.
Salivary Proteins as a Defense Against Dietary Tannins

TLDR
This work stresses the importance of gathering basic information on such items as the characteristics of unidentified TBSPs, and seasonal and geographical variations in PRP production, to support the hypothesis that species that usually ingest tannins as part of their natural diets produce high levels of PRPs.
Effect of condensed tannin ingestion in sheep and goat parotid saliva proteome.
TLDR
Although no new proteins appeared, quebracho tannin consumption increased saliva total protein concentration and produced changes in the proteome of both species, sheep and goats also presented species-specific differences in response to tANNin consumption.
Comparison of Electrophoretic Protein Profiles from Sheep and Goat Parotid Saliva
TLDR
This is the first report of a comparison of the protein salivary composition of sheep and goats and suggests that future research should be conducted to reveal a physiological function for Salivary proteins related to the differences in feeding behavior of these species.

TLDR
Analysis of saliva from three rhinoceros species from zoological gardens fed comparable, conventional zoo diets reports the first report of an induced salivary response to increased dietary tannin levels in an ungulate species.
Salivary tannin‐binding proteins are a pervasive strategy used by the folivorous/frugivorous black howler monkey
TLDR
The research details the salivary protein composition of wild and zoo‐living black howler monkeys feeding on natural versus manufactured low‐tannin diets, and examines differences in TBSPs, mainly proline‐rich proteins (PRPs), to determine whether production of these proteins is dependent on the tannin content of their food.
Tannins and ruminant nutrition
Tannins are a complex group of polyphenolic compounds found in a wide range of plant species commonly consumed by ruminants. They are conventionally classified into two major groups: the hydrolysable
Sheep and goat saliva proteome analysis: A useful tool for ingestive behavior research?
TLDR
The parotid saliva proteome of sheep and goat is presented and the potential of proteomics for investigation relating to intake behavior research is highlighted.
Tropical tannin-rich fodder intake modifies saliva-binding capacity in growing sheep.
TLDR
The saliva of hair sheep lambs consuming TR L. latisiliquum fresh fodder (TLT group) increased their tannin binding response of salivary protein (∆% turbidity) and the TPI of the different groups was similar (P>0.05).

Role of Tannins in Defending Plants Against Ruminants: Reduction in Dry Matter Digestion?
TLDR
The saliva composition of mule deer (a mixed feeder that commonly consumes browse) and domestic cattle and sheep (predominant grazers) are compared, and the higher potential of the deer saliva to neutralize tannins is related to their feeding habits.
Role of Tannins in Defending Plants Against Ruminants: Reduction in Protein Availability
TLDR
It is hypothesized that soluble phenolics that do not inhibit digestion but are absorbed and reduce intake through their toxicity are more important in defending some plant parts against ruminants than are digestion-reducing tannins.
Modulation of proline-rich protein biosynthesis in rat parotid glands by sorghums with high tannin levels.
TLDR
Amino acid analyses, electrophoretic patterns, and cell-free translations of mRNAs all confirmed that the proline-rich proteins induced by feeding high-tannin sorghum were identical to those induced by isoproterenol treatment.
Salivary proline-rich proteins

TLDR
The acidic proline-rich proteins will bind calcium with a strength which indicates that they may be important in maintaining the concentration of ionic calcium in saliva, and they can inhibit formation of hydroxyapatite, whereby growth of hydroxypatite crystals on the tooth surface in vivo may be avoided.
Binding of Condensed Tannins to-Salivary Proline-Rich Glycoproteins: The Role of Carbohydrate
Salivary proline-rich proteins have a high affinity for tannin and protect against the antinutritional effects of dietary tannins. Several of these proteins are glycosylated so we have investigated
Failure of tannic acid to inhibit digestion or reduce digestibility of plant protein in gut fluids of insect herbivores
TLDR
It is argued that there is no evidence that tannins reduce the nutritional value of an insect's food by inhibiting digestive enzymes or by reducing the digestibility of ingested proteins and, further, that the failure of tannin to interfere with digestion is readily explained on the basis of well-documented characteristics of the digestive systems of herbivorous insects.
Condensed tannin purification and characterization of tannin-associated proteins.
TLDR
The purification method can be used to isolate tannin from seeds of other plants such as legumes and consists of several discrete components which have been isolated and partially characterized.
Protein precipitation method for the quantitative determination of tannins
The tannin content of crude plant exts. or of purified prepns. was detd. by adding the sample to a std. soln. of protein, isolating the insol. tannin-protein complex, dissolving it in alk. soln., and
Induction of proline-rich glycoprotein synthesis in mouse salivary glands by isoproterenol and by tannins.
TLDR
These proline-rich glycoproteins induced in mouse parotid and submandibular glands by isoproterenol treatment have high affinities for tannins as demonstrated by competitive binding curves and appear to be identical by amino acid compositions, glycopeptide analysis, and preliminary amino acid sequencing data.
Implications of soluble tannin-protein complexes for tannin analysis and plant defense mechanisms
TLDR
It was postulated that in vivo, tannin and protein may not only form insoluble complexes with antinutritional effects, but may also form soluble complexes which have unknown metabolic effects.
