Abstract
Among the pervasive transcripts from eukaryotic genomes, a novel subset, referred to as architectural RNAs (arcRNAs), has an essential role in assembling membraneless organelles (MLOs). These arcRNAs sequester specific RNA-binding proteins (RBPs) and promote phase separation through multivalent interactions. NEAT1_2, an archetypal arcRNA, serves as a blueprint for paraspeckle architecture, characterized by a shell-and-core micelle-like configuration and immiscibility with other MLOs, relying on the cooperative contributions of distinct modular RNA domains. arcRNAs regulate gene expression through three of MLO action modes (crucible, sponge, and hub), guided by the functional blueprints embedded in arcRNA sequences. Advanced high-throughput analyses have identified thousands of arcRNA candidates, underscoring their potential in organizing transient intracellular compartments and driving dynamic cellular processes.
期刊介绍：
Launched in 1985, Trends in Genetics swiftly established itself as a "must-read" for geneticists, offering concise, accessible articles covering a spectrum of topics from developmental biology to evolution. This reputation endures, making TiG a cherished resource in the genetic research community. While evolving with the field, the journal now embraces new areas like genomics, epigenetics, and computational genetics, alongside its continued coverage of traditional subjects such as transcriptional regulation, population genetics, and chromosome biology.
Despite expanding its scope, the core objective of TiG remains steadfast: to furnish researchers and students with high-quality, innovative reviews, commentaries, and discussions, fostering an appreciation for advances in genetic research. Each issue of TiG presents lively and up-to-date Reviews and Opinions, alongside shorter articles like Science & Society and Spotlight pieces. Invited from leading researchers, Reviews objectively chronicle recent developments, Opinions provide a forum for debate and hypothesis, and shorter articles explore the intersection of genetics with science and policy, as well as emerging ideas in the field. All articles undergo rigorous peer-review.
