How RPT6 Operates in the Brain

Researchers at Virginia Tech have uncovered a new function of the Protein Molecule RPT6, previously not well-understood. It appears that RPT6 has the capacity to connect with DNA and enhance the expression of genes during memory formation. This dual functionality of RPT6, both inside and outside the proteasome complex, opens new avenues for understanding how it contributes to memory formation.

Future Research Implications with Protein Molecule

The study’s lead scientist, Keila Ferrell, emphasizes that RPT6’s discovery paves the way for in-depth investigations into the complexities of the brain, offering hope for controlling and enhancing memory in the long run. Researchers aim to explore how RPT6 precisely controls gene expression during memory, providing new directions for molecular-level insights into memory processes.

Memory Formation

Memory formation involves the expression of genes, protein composition, and the regulation of the ubiquitin-proteasome system (UPS). The catalytic component of UPS, the 26S proteasome, consists of a 20S catalytic core surrounded by four 19S regulatory caps with serine 120 (pRPT6-S120) undergoing phosphorylation in the 19S cap regulating subunit RPT6, controlling large-scale activities in the proteasome assembly.

Recently, it was demonstrated that the Protein Molecule RPT6 also operates outside the proteasome, playing a role in the hippocampus during memory formation as a transcription factor. However, little is known about the “free” function of RPT6 from the proteasome during brain activity or memory formation and whether the phosphorylation of S120 is necessary for this transcriptional control function.

Decoding RPT6: Protein Molecule Insights

Here, we utilized RNA sequencing along with novel genetic viewpoints, biochemistry, health studies, and modes of action to investigate the hypothesis that pRPT6-S120 functions independently from the proteasome to regulate gene expression during memory formation. Free RPT6, after the third downregulation of its C-terminal domain, revealed 46 gene targets in the dorsal hippocampus of rats after conditioning, where RPT6 was involved in transcriptional activation and binding.

Through CRISPR-dCas9 technology

Through CRISPR-dCas9 technology, we determined that the binding of RPT6 to DNA may be crucial for altering gene expression after learning. Additionally, changes in glycine at S120 on RPT6 in CRISPR-dCas13 technology highlighted the importance of phosphorylation at S120 for binding DNA and properly regulating transcription during memory formation.

Together, these findings suggest a new function for the Protein Molecule phosphorylation of RPT6 in controlling gene transcription during memory formation.


Understanding the intricate processes of gene expression control and phosphorylation in RPT6 during memory formation opens new avenues for research. Researchers hope that exploring the mechanisms of RPT6 at the molecular level, specifically its role as a Protein Molecule, will provide insights into understanding and treating memory-related conditions such as Alzheimer’s, dementia, and PTSD in the long term.

The identification of RPT6’s dual role marks a significant milestone in unraveling the intricacies of memory formation. This discovery not only deepens our understanding of the brain but also holds promise for future interventions in enhancing memory and treating disorders associated with memory impairments. The journey towards comprehending memory control and improvement has taken a new turn, and RPT6 stands as a key player in this exciting exploration.
