GENE INFORMATION
Gene name	POLR3A (HGNC Symbol)
Synonyms	hRPC155, RPC1, RPC155
Description	Polymerase (RNA) III (DNA directed) polypeptide A, 155kDa (HGNC Symbol)
Entrez gene summary	The protein encoded by this gene is the catalytic component of RNA polymerase III, which synthesizes small RNAs. The encoded protein also acts as a sensor to detect foreign DNA and trigger an innate immune response. [provided by RefSeq, Aug 2011]
Chromosome	10
Cytoband	q22.3
Chromosome location (bp)	77969251 - 78029545
Protein evidence	Evidence at protein level (all genes)
Ensembl	ENSG00000148606 (version 83.38)
Entrez gene	11128
UniProt	O14802 (UniProt - Evidence at protein level)
