功能：DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest core component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol III is composed of mobile elements and RPC2 is part of the core element with the central large cleft and probably a clamp element that moves to open and close the cleft. Plays a key role in sensing and limiting infection by intracellular bacteria and DNA viruses. Acts as nuclear and cytosolic DNA sensor involved in innate immune response. Can sense non-self dsDNA that serves as template for transcription into dsRNA. The non-self RNA polymerase III transcripts, such as Epstein-Barr virus-encoded RNAs (EBERs) induce type I interferon and NF- Kappa-B through the RIG-I pathway.

- Findings suggest that AP-1 factors are regulators of RNA polymerase III (Pol III)-driven 5S rRNA and U6 snRNA expression with a potential role in cell proliferation. PMID: 28488757
- Multicenter retrospective study to collect neuroradiologic, clinical, and molecular data of patients with mutations in POLR3A and POLR3B without the classic MRI phenotype: diffuse hypomyelination is not an obligatory feature of POLR3-related disorders; two distinct patterns, selective involvement of the corticospinal tracts and cerebellar atrophy, are added to the MRI presentation of POLR3-related disorders PMID: 27029625
- first reports of long deletions causing POLR3-related leukodystrophy, suggesting that deletions and duplications in POLR3A or POLR3B should be investigated in patients with a compatible phenotype PMID: 26045207
- Mutations in POLR3A or POLR3B are rare in patients with unclassified hypomyelination. PMID: 26011300
- INMAP as a model regulator of CENP-B PMID: 24633075
- These results suggest that INMAP might function through p53/p21 pathways. PMID: 25635878
- Most patients with 4H leukodystrophy carried the common c.1568T>A POLR3B mutation on one allele. PMID: 25339210
- MRI in patients with POLR3B mutations revealed smaller cerebellar structures, especially vermis, than those in POLR3A mutations. MRI also showed milder hypomyelination in patients with POLR3B mutations than those with POLR3A mutations PMID: 23643445
- Investigated POLR3A and POLR3B mutations in patients with genetically unexplained hypomyelinating leukodystrophies with features of Pol III-related leukodystrophies. Recessive mutations in POLR3A or POLR3B were uncovered in all 14 patients. PMID: 23355746
- study reports INMAP is a truncated version of POLR3B, and is up-regulated in several human cancer cell lines; results suggest that INMAP may function through the p53 and AP-1 pathways, providing a possible link of its activity with tumourigenesis PMID: 23124897
- Mutations in POLR3A and POLR3B encoding RNA Polymerase III subunits cause an autosomal-recessive hypomyelinating leukoencephalopathy PMID: 22036171
- Recessive mutations in POLR3B, encoding the second largest subunit of Pol III, cause a rare hypomyelinating leukodystrophy PMID: 22036172
