proline-rich protein BstNI subfamily 4|The protein encoded by this gene is a proline-rich salivary protein. 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012] (NCBI Entrez Gene Database, 5545)
