DNA-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. {ECO:0000269|PubMed:20154270, ECO:0000269|PubMed:35637192}. This is the function of Ensembl gene identifier ENSG00000121851 (POLR3GL, RNA polymerase III subunit GL).
