{"symbol":"PRB3","synonyms":["PRG","G1"],"name":"proline-rich protein BstNI subfamily 3","description":"This gene encodes a member of the heterogeneous family of basic, proline-rich, human salivary glycoproteins. Multiple alleles of this gene exhibiting variations in the length of the tandem repeats have been identified. The reference genome encodes the `Long` allele. The protein isoforms encoded by this gene are recognized as the `first line of oral defense` against the detrimental effects of polyphenols in the diet and pathogen infections. This gene is located in a cluster of closely related salivary proline-rich proteins on chromosome 12.
