St8sia2 Gene Summary [Mouse]

Enables alpha-N-acetylneuraminate alpha-2,8-sialyltransferase activity. Involved in sialylation. Located in early endosome and recycling endosome. Is expressed in several structures, including central nervous system; eye; future brain; genitourinary system; and gut. Orthologous to human ST8SIA2 (ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 2). [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 St8sia2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
