Spink5 Gene Summary [Rat]
Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in epidermal cell differentiation. Predicted to act upstream of or within negative regulation of serine-type peptidase activity and regulation of cell adhesion. Predicted to be located in several cellular components, including endoplasmic reticulum membrane; epidermal lamellar body; and perinuclear region of cytoplasm. Predicted to be active in extracellular region. Human ortholog(s) of this gene implicated in Netherton syndrome. Orthologous to human SPINK5 (serine peptidase inhibitor Kazal type 5).

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 Spink5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
