Protein Information (annotations from UniProt)

Database IDHIV0000685
UniProt IDO75575
Primary gene name(s)CRCP
Synonym gene name(s)unknown
Protein nameDNA-directed RNA polymerase III subunit RPC9
Protein functionDNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Specific peripheric 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 induce type I interferon and NF- Kappa-B through the RIG-I pathway, By similarity. {ECO:0000250}.; FUNCTION: Accessory protein for the calcitonin gene-related peptide, CGRP receptor. It modulates CGRP responsiveness in a variety of tissues.
Subcellular locationNucleus {ECO:0000250}. Cell membrane {ECO:0000250};
Peripheral membrane protein {ECO:0000250};
Cytoplasmic side {ECO:0000250}.
