St8sia1 Gene Summary [Mouse]
Predicted to enable alpha-N-acetylneuraminate alpha-2,8-sialyltransferase activity. Acts upstream of or within cellular response to heat and positive regulation of epithelial cell proliferation. Predicted to be located in Golgi membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hemolymphoid system gland; and sensory organ. Orthologous to human ST8SIA1 (ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 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 St8sia1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
