Usb1 Gene Summary [Mouse]
Predicted to enable poly(U)-specific exoribonuclease activity, producing 3' uridine cyclic phosphate ends. Predicted to be involved in RNA splicing and U6 snRNA 3'-end processing. Predicted to be located in intercellular bridge and nucleoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in poikiloderma with neutropenia. Orthologous to human USB1 (U6 snRNA biogenesis phosphodiesterase 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 Usb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
