POLR3A (RNA Polymerase III Subunit A): POLR3A is a critical component of RNA polymerase III, the enzyme responsible for synthesizing small RNAs, including tRNAs, 5S rRNA, and other non-coding RNAs. POLR3A is essential for the transcription of genes involved in protein synthesis and various cellular processes. Mutations in POLR3A have been linked to neurological diseases and developmental disorders, underscoring its importance in cellular function and human health....
