Htra1 Gene Summary [Rat]
Predicted to enable identical protein binding activity; molecular function activator 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); gastrointestinal system cancer (multiple); hypertension; lung adenocarcinoma; and macular degeneration (multiple). Orthologous to human HTRA1 (HtrA serine peptidase 1). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Htra1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
