Spint1 Gene Summary [Mouse]
Predicted to enable serine-type endopeptidase inhibitor activity. Acts upstream of or within chordate embryonic development; extracellular matrix organization; and placenta blood vessel development. Located in plasma membrane. Is expressed in several structures, including alimentary system; brain; extraembryonic component; hemolymphoid system; and sensory organ. Orthologous to human SPINT1 (serine peptidase inhibitor, Kunitz type 1). [provided by Alliance of Genome Resources, Jul 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 mouse Spint1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
