Polr2k Gene Summary [Mouse]
Predicted to enable DNA binding activity and zinc ion binding activity. Predicted to contribute to DNA-directed RNA polymerase activity. Acts upstream of or within transcription by RNA polymerase II. Predicted to be located in nucleus. Predicted to be part of RNA polymerase I complex; RNA polymerase II, core complex; and RNA polymerase III complex. Is expressed in several structures, including cerebral cortex; nose; submandibular gland primordium; thymus primordium; and tooth. Orthologous to human POLR2K (RNA polymerase II, I and III subunit K). [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 Polr2k often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
