Basic salivary proline-rich protein 3 is a protein that in humans is encoded by the PRB3 gene .[ 3] [ 4]
The protein encoded by this gene is a proline -rich salivary protein. It is a major constituent of parotid saliva . This protein is proposed to act as a bacterial receptor. This gene and five other genes that also encode salivary proline-rich proteins (PRPs), as well as a gene encoding a lacrimal gland PRP, form a PRP gene cluster in the chromosomal 12p13 region.[ 4]
