Cst9 Gene Summary [Mouse]
Predicted to enable cysteine-type endopeptidase inhibitor activity. Involved in antimicrobial humoral response. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including gut; heart; reproductive system; and urogenital ridge. Orthologous to several human genes including CST9L (cystatin 9 like). [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 Cst9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
