Also known as: RPP29
Summary: This gene encodes one of the protein subunits of the small nucleolar ribonucleoprotein complexes: the endoribonuclease for mitochondrial RNA processing complex and the ribonuclease P complex. The encoded protein is localized to the nucleus and associates directly with the RNA component of these complexes. This protein is involved in processing of precursor RNAs. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2009]
Expression: Ubiquitous expression in testis (RPKM 7.0), lymph node (RPKM 6.7) and 25 other tissues See more

Rpp29 regulates H3.3-mediated epigenetic mechanisms by processing a transcribed signal that recruits H3.3 to its incorporation sites
Title: Rpp29 regulates histone H3.3 chromatin assembly through transcriptional mechanisms.
Results demonstrate that Rpp29 promotes homology-directed repair of double-strand breaks. It is rapidly and transiently recruited to laser-microirradiated DNA sites.
Title: A role of human RNase P subunits, Rpp29 and Rpp21, in homology directed-repair of double-strand breaks.
Collectively, the present results suggest that PhoRpp21 binds the loop between P11 and P12 helices through overall positively charged clusters on the surface of the complex and serves as a scaffold for PhoRpp29 to optimize structural conformation of its N-terminal helix (alpha2) in PhoRpp21, as well as C-terminal residues in PhoRpp29, for RNase P activity.
Title: Functional characterization of archaeal homologs of human nuclear RNase P proteins Rpp21 and Rpp29 provides insights into the molecular basis of their cooperativity in catalysis.
Rpp29 represses H3.3 nucleosome deposition, a finding with implications for epigenetic regulation.
Title: RNase P protein subunit Rpp29 represses histone H3.3 nucleosome deposition.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (2) lacks an exon in the coding region, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
