POLRMT
RNA polymerase mitochondrial
Pathway candidate — not linked to PFS or PSSD by any record here
Gene summary
A protein-coding gene on chromosome 19 (basal transcription machinery). 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.

- Protein
DNA-directed RNA polymerase, mitochondrial
- Function
DNA-dependent RNA polymerase catalyzes the transcription of mitochondrial DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of the mitochondrial transcription initiation complex, composed at least of TFB2M, TFAM and POLRMT that is required for basal transcription of mitochondrial DNA. In this complex, TFAM recruits POLRMT to a specific promoter whereas TFB2M induces structural changes in POLRMT to enable promoter opening and trapping of the DNA non-template strand. Has DNA primase activity. Catalyzes the synthesis of short RNA primers that are necessary for the initiation of lagging-strand DNA synthesis from the origin of light-strand DNA replication (OriL).
- Subcellular location
Mitochondrion.
- Associated conditions
Combined oxidative phosphorylation deficiency 55 (COXPD55).

Why its pathway is in the library
Core RNA polymerase II machinery; general cellular function with no direct post-drug-syndrome link established.
Written for the whole basal transcription family, not for POLRMT specifically.
Mentioned in 0 corpus records
No corpus record names POLRMT directly yet. It is in the library because it sits in a pathway the corpus tracks (Basal transcription).
