Rpb12, rpc10, RPC11, ABC10 alpha, Rpc11p
This gene encodes a small essential subunit of RNA polymerase III, the polymerase responsible for synthesizing transfer and small ribosomal RNAs in eukaryotes. The carboxy-terminal domain of this subunit shares a high degree of sequence similarity to the carboxy-terminal domain of an RNA polymerase II elongation factor. This similarity in sequence is supported by functional studies showing that this subunit is required for proper pausing and termination during transcription. Pseudogenes of this gene are found on chromosomes 13 and 17.[provided by RefSeq, Jul 2010] (from
Thomm et al., Regensburg, Germany. In Mol Microbiol, 2009
The general subunit of all three eukaryotic RNA polymerases, Rpb12, and subunit P of the archaeal enzyme show sequence similarities in their N-terminal zinc ribbon and some highly conserved residues in the C-terminus.

Structural considerations predict that the slj Pol3rb deletion might impair its interaction with Polr3k, the ortholog of an essential yeast Pol III subunit, Rpc11, which promotes RNA cleavage and Pol III recycling.
Dietrich et al., Durham, United States. In Curr Genet, 2005
We hypothesize that uORFs in the UTR of RPC11, TPK1, FOL1, WSC3, and MKK1 may have translational regulatory roles while uORFs in the 5' UTR of ECM7 and IMD4 have little effect on translation under the conditions tested.
Proudfoot et al., Oxford, United Kingdom. In Proc Natl Acad Sci U S A, 2004
The homology of Rpa12p to the small subunit Rpb9p of Pol II and Rpc11p of Pol III, both implicated in transcriptional termination, points to a common termination mechanism for all three classes of RNA polymerase.

Among these effects were the upregulation of two nuclear proteins encoding a Y'-helicase (a subtelomerically encoded protein whose function is to maintain telomeres) and a suppressor of rpc10 and rpb40 mutations (both rpc10 and rpb40 encode RNA polymerase subunits).
Ishihama et al., Mishima, Japan. In Genes Cells, 2001
To obtain an insight into the regulation of synthesis of these 12 Pol II subunits, Rpb1 to Rpb12, in the fission yeast Schizosaccharomyces pombe, we analysed the transcriptional organization of the rpb genes by use of the oligo capping method, and determined mRNA levels by quantitative competitive PCR assay.
Weinzierl et al., London, United Kingdom. In Nucleic Acids Res, 2000
The F and P subunits present in archaeal RNA polymerases were only recently identified in a purified archaeal RNA polymerase preparation and, on the basis of localized sequence homologies, tentatively identified as archaeal versions of the eukaryotic RPB4 and RPB12 RNA polymerase subunits, respectively.
Marck et al., Gif-sur-Yvette, France. In J Biol Chem, 1999
A thermosensitive mutation in the C terminus region of ABC10alpha (rpc10-30) was found to be selectively suppressed by overexpression of a mutant form of tau131 (tau131-DeltaTPR2) that lacks the second TPR repeat.
