POLRMT

DNA-directed RNA polymerase, mitochondrial is an is_associated_with::enzyme that in humans is encoded by the POLRMT is_associated_with::gene.

Function
This gene encodes a mitochondrial DNA-directed is_associated_with::RNA polymerase. The gene product is responsible for mitochondrial gene expression as well as for providing RNA primers for initiation of replication of the mitochondrial genome. Although this polypeptide has the same function as the three nuclear DNA-directed RNA polymerases, it is more closely related to RNA polymerases of is_associated_with::bacteriophage and mitochondrial polymerases of lower is_associated_with::eukaryotes.
