Prps1 Gene Summary [Mouse]
Enables ribose phosphate diphosphokinase activity. Involved in 5-phosphoribose 1-diphosphate biosynthetic process and pentose-phosphate shunt. Is active in cytosol. Is expressed in central nervous system; heart; inner ear; liver; and retina. Human ortholog(s) of this gene implicated in Arts syndrome; X-linked deafness 1; X-linked recessive disease (multiple); gout; and retinitis pigmentosa. Orthologous to human PRPS1 (phosphoribosyl pyrophosphate synthetase 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 Prps1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
