DNA-Directed RNA Polymerase III Subunit RPC10 (POLR3K) Human Recombinant Protein

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs. 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.

The RNA cleavage activity of RNA polymerase III is mediated by an essential TFIIS-like subunit and is important for transcription termination.Chedin S., Riva M., Schultz P., Sentenac A., Carles C.Genes Dev. 12:3857-3871(1998) Molecular identification and characteristics of hRPC11, the smallest specific subunit of human RNA polymerase III.Spakovskii G.V., Lebedenko E.N.Bioorg.

Small volumes of POLR3K recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS969596 is a recombinant protein targeting POLR3K. Also known as Recombinant Human DNA-directed RNA polymerase III subunit RPC10. Host: E Coli or Yeast or Baculovirus or Mammalian Cell.
