NAP1 plays a positive regulatory role in plant rDNA transcription, possibly through derepression of the negative effect of the RPS6-HD2B complex.
Title: Identification of nucleosome assembly protein 1 (NAP1) as an interacting partner of plant ribosomal protein S6 (RPS6) and a positive regulator of rDNA transcription.

the interaction between RPS6 and AtHD2B brings about a change in the chromatin structure of rDNA and thus plays an important role in linking TOR signaling to rDNA transcription and ribosome biogenesis in plants.
Title: Ribosomal protein S6, a target of rapamycin, is involved in the regulation of rRNA genes by possible epigenetic changes in Arabidopsis.

RPS6 function is indispensable for cell survival and the two Arabidopsis RPS6 proteins are functionally indistinguishable. [RPS6A]
Title: The two Arabidopsis RPS6 genes, encoding for cytoplasmic ribosomal proteins S6, are functionally equivalent.
