General description

Ribosomal RNA-processing protein 8 (UniProt: O43159; also known as Cerebral protein 1, Nucleomethylin) is encoded by the RRP8 (also known as KIAA0409, NML, hucep-1) gene (Gene ID: 23378) in human. Ribosome biosynthesis is one of the most energy-consuming cellular process, which adapts to changes in intracellular energy status. Ribosomal RNA-processing protein 8 is a novel nuclear protein that serves as an essential component of the energy-dependent nucleolar silencing) complex (eNoSC) that mediates silencing of rDNA in response to intracellular energy status and acts by recruiting histone-modifying enzymes. The eNoSC complex is able to sense the energy status of cell: upon glucose starvation or upon elevation of NAD+/NADP+ ratio and activates SIRT1 that leads to deacetylation of histone H3 followed by dimethylation of H3 at Lysine 9 (H3K9me2) by SUV39H1 and the formation of silent chromatin in the rDNA locus. In the complex, RRP8 binds to H3K9me2 and probably acts as a methyltransferase.

Specificity

Clone 5C7.1 specifically detects Ribosomal RNA-processing protein 8. It targets an epitope with in the C-terminal half.

Immunogen

GST-tagged recombinant fragment corresponding to 98 amino acids from the C-terminal half of human Ribosomal RNA-processing protein 8.
