Protein
DNA-directed RNA polymerases II and IV subunit 5A
Organism
Arabidopsis thaliana
Function
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. Component of RNA polymerase IV which mediates short-interfering RNAs (siRNA) accumulation and subsequent RNA-directed DNA methylation-dependent (RdDM) transcriptional gene silencing (TGS) of target sequences.
Similarity
Belongs to the archaeal RpoH/eukaryotic RPB5 RNA polymerase subunit family.
