Protein Name:
DNA-directed RNA polymerase I subunit 2
|
UniprotKB/SwissProt ID: F4I366 (F4I366)
Gene Name:
NRPA2
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest core component of RNA polymerase I which synthesizes ribosomal RNA precursors. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol I is composed of mobile elements and NRPA2 is part of the core element with the central large cleft and probably a clamp element that moves to open and close the cleft Essential for the completion of the three rounds of mitosis in female megaspores required for the development of mature gametophytes
