Polrmt Gene Summary [Mouse]
Enables sequence-specific DNA binding activity. Predicted to be involved in transcription initiation at mitochondrial promoter. Located in mitochondrion. Part of protein-containing complex. Is expressed in early conceptus; limb mesenchyme; and secondary oocyte. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 55. Orthologous to human POLRMT (RNA polymerase mitochondrial). [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 Polrmt often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
