Abstract—RNA polymerase III synthesizes a wide range of noncoding RNAs shorter than 400 nucleotides in length. These RNAs are involved in protein synthesis (tRNA, 5S rRNA, and 7SL RNA), maturation, and splicing of different types of RNA (RPR, MRP RNA, and U6 snRNA), regulation of transcription (7SK RNA), replication (Y RNA), and intracellular transport (vault RNA). BC200 and BC1 RNA genes are transcribed by RNA polymerase III in neurons only where these RNAs regulate protein synthesis. Mutations in the regulatory elements of the genes transcribed by RNA polymerase III as well as in transcription factors of this RNA polymerase are associated with the development of a number of diseases, primarily oncological and neurological. In this regard, the mechanisms of regulation of the expression of the genes containing various RNA polymerase III promoters were actively studied. This review describes the structural and functional classification of polymerase III promoters, as well as the factors involved in the regulation of promoters of different types. A number of examples demonstrate the role of the described factors in the pathogenesis of human diseases.
期刊介绍：
Molecular Biology is an international peer reviewed journal that covers a wide scope of problems in molecular, cell and computational biology including genomics, proteomics, bioinformatics, molecular virology and immunology, molecular development biology, molecular evolution and related areals. Molecular Biology publishes reviews, experimental and theoretical works. Every year, the journal publishes special issues devoted to most rapidly developing branches of physical-chemical biology and to the most outstanding scientists.
