Sfn Gene Summary [Mouse]
Enables phosphoprotein binding activity and protein kinase binding activity. Involved in several processes, including cAMP/PKA signal transduction; establishment of skin barrier; and protein export from nucleus. Acts upstream of or within several processes, including keratinocyte differentiation; negative regulation of cell population proliferation; and regulation of cyclin-dependent protein serine/threonine kinase activity. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in transitional cell carcinoma and vulva squamous cell carcinoma. Orthologous to human SFN (stratifin). [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 Sfn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
