Gene Information
human ... RRP1(8568)
General description
The gene RRP1 (ribosomal RNA processing protein-1 homolog A) has been mapped to human chromosome 21q22.3. The protein is a human homologue of the yeast ribosomal RNA processing protein RRP1. The protein has been localized to the nucleoli and at the periphery of the chromosomes.

Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
In nucleoli, ribosomal RNA processing protein-1 homolog A (RRP1) is excluded from the rRNA transcription sites, which accumulates in the granular external domain and mainly co-localizes with nucleolar proteins such as B23 which are involved in late processing step. The perinuclear bodies sequentially recruit fibrillarin, nucleoli and RRP1 together with B23 during formation of the nucleolus at the end of mitosis. p32, fibrillarin and RRP1 play key roles in the separation of pre-90S particle into pre-40S and pre-60S particles. RRP1 is also involved in the cleavage at site 2 in internal transcribed space1 of pre-rRNAs at early stages of human ribosome biogenesis. Together the above two events are essential to produce the small and large ribosomal subunits in human cells.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

To understand how nuclear machineries are targeted to accurate locations during nuclear assembly, we investigated the pathway of the ribosomal RNA (rRNA) processing machinery towards ribosomal genes (nucleolar organizer regions [NORs]) at exit of mitosis. To follow in living cells

The Saccharomyces cerevisiae gene RRP1 encodes an essential, evolutionarily conserved protein necessary for biogenesis of 60S ribosomal subunits. Processing of 27S pre-ribosomal RNA to mature 25S rRNA is blocked and 60S subunits are deficient in the temperature-sensitive rrp1-1 mutant. We

Ribosome biogenesis starts with transcription of the large ribosomal RNA precursor (47S pre-rRNA), which soon combines with numerous factors to form the 90S pre-ribosome in the nucleolus. Although the subsequent separation of the pre-90S particle into pre-40S and pre-60S particles

We report the molecular characterization of a novel nucleolar protein, Nop52, and its subcellular distribution during the cell cycle and nucleologenesis. This protein was originally identified with human autoantibodies which were subsequently used to clone its corresponding cDNA. Transfection experiments
