Polr1e Gene Summary [Mouse]
Enables RNA polymerase I general transcription initiation factor binding activity. Acts upstream of or within RNA polymerase I preinitiation complex assembly. Located in nucleolus. Part of RNA polymerase I complex. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Orthologous to human POLR1E (RNA polymerase I subunit E). [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 Polr1e often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
