Gba2 Gene Summary [Mouse]
Enables glucosylceramidase activity; glucosyltransferase activity; and steryl-beta-glucosidase activity. Involved in several processes, including glucosylceramide catabolic process; lipid glycosylation; and regulation of protein polymerization. Located in Golgi membrane; cytosol; and endoplasmic reticulum membrane. Is expressed in several structures, including central nervous system; dorsal root ganglion; epidermis; liver; and neural retina. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 46. Orthologous to human GBA2 (glucosylceramidase beta 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 Gba2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
