POLRMT - RNA polymerase mitochondrial Gene
Also Known as APOLMT; MTRNAP; MTRPOL; COXPD55; h-mtRPOL
Species: Homo sapiens
About POLRMT
This gene has 8 transcripts (splice variants), 198 orthologues and is associated with 1 phenotype. Broad expression in testis (RPKM 15.0), kidney (RPKM 8.1) and 25 other tissues.
Summary
This gene encodes a mitochondrial DNA-directed 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 phage and mitochondrial polymerases of lower eukaryotes.
