• B. SMCR8-WDR41 complex
  The SMCR8-WDR41 complex is a protein assembly that partners with C9orf72 to regulate autophagy and lysosomal function, particularly in the context of neurodegenerative disease mechanisms.
• C. RNA polymerase II
  RNA polymerase II is the eukaryotic enzyme complex responsible for transcribing DNA into messenger RNA and many non-coding RNAs, playing a central role in gene expression.
• D. CTCF
  CTCF is a state prison facility in Colorado that houses incarcerated individuals under the jurisdiction of the Colorado Department of Corrections.
• E. Mastermind-like coactivator
  Mastermind-like coactivator is a transcriptional coactivator protein family that partners with Notch intracellular domains to activate Notch target gene expression in developmental and cell-fate signaling pathways.
