Polymerase III Polypeptide K, known as PORL3K, is a small vital subunit of RNA polymerase III. The carboxy-terminal domain of PORL3K owns a sequence which is very similar to the carboxy-terminal domain of an RNA polymerase II elongation factor. PORL3K takes part in sensing and limiting infection by intracellular bacteria and DNA viruses. PORL3K is also plays a role as nuclear and cytosolic DNA sensor which takes part in the innate immune response.

POLR3K Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 131 amino acids (1-108 a.a) and having a molecular mass of 14.7kDa.POLR3K is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

UniProt Protein Function:POLR3K: 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. Belongs to the archaeal RpoM/eukaryotic RPA12/RPB9/RPC11 RNA polymerase family.

NCBI Summary: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]
