Predicted to enable identical protein binding activity and serine-type endopeptidase activity. Involved in dentinogenesis; negative regulation of defense response to virus; and positive regulation of epithelial cell proliferation. Located in collagen-containing extracellular matrix. Human ortholog(s) of this gene implicated in CADASIL (multiple); hypertension; and macular degeneration (multiple). Orthologous to human HTRA1 (HtrA serine peptidase 1).
