Summary of "RNA and protein-based nanodevices for mammalian post-transcriptional circuits."

Mammalian synthetic gene circuits have promise in biological and medical research due to their capability of controlling cellular functions. Especially, post-transcriptional circuits are growing in interest because of features that include compatibility and superior safety. RNA-based molecular nanodevices are often a core component in these circuits. RNA nanodevices that act as translational controllers should be suitable for designing genetic circuits that execute complex functions. In this review, we introduce recent progress in designing synthetic RNA-based circuitry and building mammalian post-transcriptional networks.

Medical and Biotech [MESH] Definitions

Post-transcriptional biological modification of messenger, transfer, or ribosomal RNAs or their precursors. It includes cleavage, methylation, thiolation, isopentenylation, pseudouridine formation, conformational changes, and association with ribosomal protein.

RNA transcripts of the DNA that are in some unfinished stage of post-transcriptional processing (RNA PROCESSING, POST-TRANSCRIPTIONAL) required for function. RNA precursors may undergo several steps of RNA SPLICING during which the phosphodiester bonds at exon-intron boundaries are cleaved and the introns are excised. Consequently a new bond is formed between the ends of the exons. Resulting mature RNAs can then be used; for example, mature mRNA (RNA, MESSENGER) is used as a template for protein production.

A forkhead box transcription factor and transcriptional activator which triggers type 1 programmed cell death (APOPTOSIS) in the absence of APOPTOSIS INHIBITING PROTEINS, including neuronal cell death induced by OXIDATIVE STRESS. It recognizes and binds to the DNA sequence 5'-(AG)TAAA(TC)A-3' and also functions in post-transcriptional regulation of the c-MYC PROTO-ONCOGENE.

A class of untranslated RNA molecules that are typically greater than 200 nucleotides in length and do not code for proteins. Members of this class have been found to play roles in transcriptional regulation, post-transcriptional processing, CHROMATIN REMODELING, and in the epigenetic control of chromatin.

A family of RRM PROTEINS that are homologues of ELAV protein, Drosophila. They were initially identified in humans as the targets of autoantibodies in patients with PARANEOPLASTIC ENCEPHALOMYELITIS. They regulate GENE EXPRESSION at the post-transcriptional level.
