RRP4 also known as RRP4 homolog is a component of the exosome complex a multi-protein complex involved in RNA processing. RRP4 plays an important mechanical role in RNA degradation and it is essential for maintaining RNA stability by facilitating the 3' to 5' exonucleolytic trimming of RNA molecules. This protein has a molecular mass of approximately 26 kDa and is widely expressed in the nucleus and cytoplasm where it participates in various RNA processing tasks.

Biological function summary

RRP4 performs an important role in RNA metabolism and is a vital constituent of the exosome complex which is responsible for RNA processing degradation and surveillance. The exosome complex acts in RNA quality control targeting malformed RNAs for degradation. RRP4 contributes to rRNA processing and maturation by forming stable interactions within the nucleolus. This activity ensures the accuracy and functionality of ribosomal RNA supporting the cell's protein synthesis machinery.

Pathways

RRP4 plays a critical function in the RNA processing pathways and is involved in rRNA and mRNA turnover. RRP4 interconnects with pathways involving exosome components like RRP6 and DIS3 which also contribute to RNA decay. Processing of rRNA by mechanisms involving RRP4 ensures the quality of ribosome assembly which is essential for translation and cellular homeostasis.

Improper function of the exosome complex including RRP4 associates with neurological conditions such as pontocerebellar hypoplasia and certain forms of cancer. RRP4 alongside proteins like RRP6 and DIS3 can accumulate mutations affecting exosome functionality. This can lead to disrupted RNA processing and accumulation of faulty RNA products contributing to disease pathogenesis. Understanding these interactions is vital for developing therapeutic approaches targeting such conditions.

Target data

Non-catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. In the nucleus, the RNA exosome complex is involved in proper maturation of stable RNA species such as rRNA, snRNA and snoRNA, in the elimination of RNA processing by-products and non-coding 'pervasive' transcripts, such as antisense RNA species and promoter-upstream transcripts (PROMPTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. The RNA exosome may be involved in Ig class switch recombination (CSR) and/or Ig variable region somatic hypermutation (SHM) by targeting AICDA deamination activity to transcribed dsDNA substrates. In the cytoplasm, the RNA exosome complex is involved in general mRNA turnover and specifically degrades inherently unstable mRNAs containing AU-rich elements (AREs) within their 3' untranslated regions, and in RNA surveillance pathways, preventing translation of aberrant mRNAs. It seems to be involved in degradation of histone mRNA. The catalytic inactive RNA exosome core complex of 9 subunits (Exo-9) is proposed to play a pivotal role in the binding and presentation of RNA for ribonucleolysis, and to serve as a scaffold for the association with catalytic subunits and accessory proteins or complexes. EXOSC2 as peripheral part of the Exo-9 complex stabilizes the hexameric ring of RNase PH-domain subunits through contacts with EXOSC4 and EXOSC7.
