Summary: Predicted to enable serine-type endopeptidase activity. Acts upstream of or within amelogenesis; extracellular matrix disassembly; and protein catabolic process. Predicted to be located in extracellular region. Predicted to be active in extracellular space and secretory granule. Is expressed in alimentary system; male reproductive gland or organ; and skin. Human ortholog(s) of this gene implicated in amelogenesis imperfecta type 2A1 and prostate cancer. Orthologous to human KLK4 (kallikrein related peptidase 4).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
