EXOSC2 Activators

EXOSC2, also known as Ribonuclease PH 2 (RPH2) or Exosome Component 2, is a protein encoded by the EXOSC2 gene in humans. It's a key part of the exosome complex, a multi-protein complex essential for the 3' degradation of a variety of RNA molecules.The exosome complex is involved in numerous RNA processing and degradation tasks, contributing to the maturation of structured RNAs, such as rRNA, snRNA, and snoRNA, and the degradation of RNA, including faulty mRNA and rRNA. EXOSC2, along with other core exosome components, participates in these processes by providing catalytic activity for the complex.

EXOSC2 is a phosphorolytic exoribonuclease, which means it degrades RNA molecules from the 3' end, one nucleotide at a time, using a phosphate molecule in the process. It's critical for the overall function of the exosome complex, playing a role in both nuclear and cytoplasmic RNA metabolism.Alterations in EXOSC2 and the exosome complex have been associated with various diseases. For instance, mutations in the EXOSC2 gene have been linked to Pontocerebellar Hypoplasia, a group of genetic neurodegenerative disorders with prenatal onsetThe role of EXOSC2 and the exosome complex in RNA metabolism also makes them interesting targets in cancer research. The regulation of RNA stability and degradation is crucial for proper cell function, and dysregulation can lead to the development and progression of cancer.
