Abstract

Statherin is a 43 residue, tyrosine—rich phosphoprotein which possesses the ability to inhibit both spontaneous and secondary precipitation (crystal growth) of calcium phosphate salts from supersaturation solutions. Because of this unusual property it has been proposed that its function is to prevent precipitation from salivary secretions, which are normally super saturated with respect to most calcium phosphate salts, and help provide a protective and stabilizing environment for tooth surfaces. RNA was isolated from human submandibular and macaque parotid glands and was separated into polyA—enriched and polyA— deficient fractions by chromatography on oligo(dT)cellulose. of these RNA fractions stimulated methionine incorporation polypeptides in a rabbit reticulocyte lysate translation system. Antiserum raised in response to human statherin was used for immunoprecipitation of pro—statherin to separate it from other salivary proteins synthesized in the translation reactions. Cross—reactivity occurred between human and macaque statherin.
