Ribosomal RNA-processing protein 8 is a protein that in humans is encoded by the RRP8 gene.[5][6] The RRP8 protein is involved in regulating and silencing ribosomal DNA as part of the energy-dependent nucleolar silencing complex (eNoSC).[7] In particular, a component of the eNoSC complex, SIRT1, detects glucose starvation via NAD+/NADP+ levels, leading to the deacetylation of histone H3.[7] This triggers another subunit, SUV39H1, to perform dimethylation of H3 at 'Lys-9' (denoted H3K9me2), leading to a silent DNA state.[7] As part of this complex, the RRP8 protein binds to H3K9me2, and may act as methyltransferase, but its substrate(s) are currently unknown.[7]
