Prp2 - proline rich protein 2

This gene encodes a member of the heterogeneous family of proline-rich salivary glycoproteins. The expression of this gene is dramatically induced in the parotid and submandibular glands of mice by beta-adrenergic stimulation. The encoded protein serves an important dental function by protecting mice against toxic dietary polyphenols such as tannins and influence the visco-elastic properties of the mucus. This gene is located in a cluster of closely related salivary proline-rich proteins on chromosome 6. [provided by RefSeq, Nov 2015]
