The human PRSS17 (serine protease 17) gene, which is located on chromosome 19q in a cluster of genes encoding serine proteases, has been variously designated enamel matrix serine proteinase 1 (EMSP1), prostase, KLK4, and KLK-L1. We have cloned and characterized the mouse and human PRSS17 genes. Both have six exons and five introns. The mouse PRSS17 gene sequence is 10134bp; the human sequence is 7115bp. Computer analysis of the mouse PRSS17 gene sequence upstream of the translation initiation codon identified two potential transcription initiation sites, at nucleotides 2878 and 2336. The first nucleotide of the reported mouse PRSS17 cDNA sequence corresponds to position 2352 on the gene, only 16 bases downstream from one of the putative transcription initiation sites. Repetitive DNA sequences from the MSR1 family are found in both the mouse and human PRSS17 genes. Additionally, the human PRSS17 gene contains Tigger2, MER8, and Alu repetitive sequences. Phylogenetic analyses of human and rodent proteases suggest that the PRSS17 protein is not a member of the kallikrein family of serine proteases but that the PRSS17 gene may have originated prior to the divergence of the kallikrein and trypsin families of proteases. To better characterize the timing of PRSS17 expression in developing teeth, we performed in-situ hybridization on postnatal day 3 developing mouse mandibular incisors. PRSS17 mRNA was not detected in secretory stage ameloblasts but could be detected in odontoblasts, while transition-stage and maturation-stage ameloblasts were strongly positive. This pattern supports a role for the PRSS17 protein in the degradation of enamel proteins.
