Ext2 Gene Summary [Mouse]

Enables N-acetylglucosaminyl-proteoglycan 4-beta-glucuronosyltransferase activity; glucuronosyl-N-acetylglucosaminyl-proteoglycan 4-alpha-N-acetylglucosaminyltransferase activity; and protein homodimerization activity. Acts upstream of or within with a positive effect on gene expression; protein N-linked glycosylation; and sulfation. Acts upstream of or within several processes, including multicellular organismal-level water homeostasis; proteoglycan biosynthetic process; and skeletal system development. Located in Golgi apparatus and endoplasmic reticulum. Is expressed in several structures, including alimentary system; central nervous system; ear; genitourinary system; and respiratory system. Used to study hereditary multiple exostoses. Orthologous to human EXT2 (exostosin glycosyltransferase 2). [provided by Alliance of Genome Resources, Apr 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 Ext2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
