Summary
POLR3F (RNA polymerase III subunit F, HGNC:15763) is a protein-coding gene on chromosome 20p11.23, encoding DNA-directed RNA polymerase III subunit RPC6 (Q9H1D9). DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. It is a common-essential gene (DepMap: required in 99.4% of cancer cell lines).
The protein encoded by this gene is one of more than a dozen subunits forming eukaryotic RNA polymerase III (RNA Pol III), which transcribes 5S ribosomal RNA and tRNA genes. This protein has been shown to bind both TFIIIB90 and TBP, two subunits of RNA polymerase III transcription initiation factor IIIB (TFIIIB). Unlike most of the other RNA Pol III subunits, the encoded protein is unique to this polymerase. Alternative splicing results in multiple transcript variants.

Literature-anchored findings (GeneRIF, showing 1)
- We also show that endogenous microDNA associate with RNA polymerases subunits, POLR2H and POLR3F. Together, these results suggest that microDNA may modulate gene expression through the production of both known and novel regulatory small RNA. (PMID:30828735)

Function. DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Specific peripheric component of RNA polymerase III (Pol III) which synthesizes small non-coding RNAs including 5S rRNA, snRNAs, tRNAs and miRNAs from at least 500 distinct genomic loci. Part of POLR3C/RPC3-POLR3F/RPC6-POLR3G/RPC7 heterotrimer that coordinates the dynamics of Pol III stalk and clamp modules during the transition from apo to elongation state. Pol III plays a key role in sensing and limiting infection by intracellular bacteria and DNA viruses, including varicella zoster virus. Acts as a nuclear and cytosolic DNA sensor detecting AT-rich DNA, 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. Preferentially binds double-stranded DNA (dsDNA).
Subunit / interactions. Component of the RNA polymerase III complex consisting of 17 subunits: a ten-subunit horseshoe-shaped catalytic core composed of POLR3A/RPC1, POLR3B/RPC2, POLR1C/RPAC1, POLR1D/RPAC2, POLR3K/RPC10, POLR2E/RPABC1, POLR2F/RPABC2, POLR2H/RPABC3, POLR2K/RPABC4 and POLR2L/RPABC5; a mobile stalk composed of two subunits POLR3H/RPC8 and CRCP/RPC9, protruding from the core and functioning primarily in transcription initiation; and additional subunits homologous to general transcription factors of the RNA polymerase II machinery, POLR3C/RPC3-POLR3F/RPC6-POLR3G/RPC7 heterotrimer required for transcription initiation and POLR3D/RPC4-POLR3E/RPC5 heterodimer involved in both transcription initiation and termination. Directly interacts with POLR3C. Interacts with TBP and TFIIIB90 and GTF3C4. Interacts with MAF1. As part of the RNA polymerase III complex, interacts with PKP2.
Subcellular location. Nucleus.
Disease relevance. Immunodeficiency 101, varicella zoster virus-specific (IMD101) [MIM:619872] An autosomal dominant immunologic disorder characterized by reactivation of varicella zoster virus (VZV) infection in adulthood after primary childhood infection with VZV. The viral reactivation manifests as central nervous system vasculitis with stroke-like episodes and lacunar infarcts on brain imaging. Features include headache, hemiparesis, impaired balance, and other neurologic signs. The disease may be caused by variants affecting the gene represented in this entry.
Domain organisation. The [4FE-4S] cluster-binding domain adopts a globular structure that serves as an interaction hub that connects the POLR3C/RPC3-POLR3F/RPC6-POLR3G/RPC7 heterotrimer to the Pol III core.
Similarity. Belongs to the eukaryotic RPC34/RPC39 RNA polymerase subunit family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 75 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
