Summaries for PRB3 Gene

Entrez Gene Summary for PRB3 Gene

  • 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. [provided by RefSeq, Nov 2015]

Post-translational modifications for PRB3 Gene

  • N- and O-glycosylated; contains about 50% carbohydrate. This is composed of highly fucosylated N-linked saccharides, the major structure is a biantennary asialosaccharide containing 2 fucose residues on one antenna and an unsubstituted terminal lactosamine sequence on the other. The Gram-negative bacterium F.nucleatum binds to carbohydrates containing unsubstituted GalBeta1,4GlcNAc residues.
  • Proteolytically cleaved at the tripeptide Xaa-Pro-Gln, where Xaa in the P(3) position is mostly lysine. The endoprotease may be of microbial origin. Besides on the N-terminal of mature PRB3, pyroglutamate formation found on at least Gln-67, Gln-88, Gln-214 and Gln-295.
  • The Gl-8 variant contains an interchain disulfide bond with salivary peroxidase.
  • Glycosylation at Asn 66, Asn 87, Ser 89, Asn 108, Asn 129, Asn 150, Asn 171, Asn 192, Asn 213, and Asn 255
