RNA Regulatory Networks: Key Hubs in the Panorama of Cancer and Emerging Therapeutic Targets
MedComm, Volume 7, Issue 3, March 2026.RNA regulatory networks play a crucial role in the initiation and progression of cancer through various modes of RNA interactions. Notably, circulating RNAs have emerged as potential biomarkers, while targeted interventions in RNA regulatory networks facilitate precise therapeutic strategies. ABSTRACT Cancer is a global health challenge. The initiation

Brr2p-mediated conformational rearrangements in the spliceosome during activation and substrate repositioning [PDF]
, 2012 Brr2p is one of eight RNA helicases involved in pre-mRNA splicing. Detailed understanding of the functions of Brr2p and other spliceosomal helicases has been limited by lack of knowledge of their in vivo substrates. To address this, sites of direct Brr2p–

Assembly of Snu114 into U5 snRNP requires Prp8 and a functional GTPase domain [PDF]
RNA, 2006 Snu114 is a U5 snRNP protein essential for pre-mRNA splicing. Based on its homology with the ribosomal translocase EF-G, it is thought that GTP hydrolysis by Snu114 induces conformational rearrangements in the spliceosome. We recently identified allele-specific genetic interactions between SNU114 and genes encoding three other U5 snRNP components, Prp8

Human Cyclophilins—An Emerging Class of Drug Targets
Medicinal Research Reviews, Volume 46, Issue 2, Page 475-512, March 2026.ABSTRACT Cyclophilins are a family of enzymes with peptidyl‐prolyl isomerase activity found in all cells of all organisms. To date, 17 cyclophilin isoforms have been identified in the human body, participating in diverse biological processes. Consequently, cyclophilins have emerged as promising targets for drug development to address a wide array of ...

Sad1 Counteracts Brr2-Mediated Dissociation of U4/U6.U5 in Tri-snRNP Homeostasis [PDF]
Molecular and Cellular Biology, 2014 The yeast Sad1 protein was previously identified in a screen for factors involved in the assembly of the U4/U6 di-snRNP particle. Sad1 is required for pre-mRNA splicing both in vivo and in vitro, and its human orthologue has been shown to associate with U4/U6.U5 tri-snRNP.

The FEBS Journal, Volume 293, Issue 5, Page 1323-1340, March 2026.Human SART3 has two RRM domains to engage with U6 snRNA for spliceosome recycling. This study reports solution structures of SART3 RRM domains and investigates the interaction between RRM and U6 snRNA. SART3 binds to the asymmetric bulge of U6 snRNA as a dimer via conserved positively charged surfaces.

Minor introns are embedded molecular switches regulated by highly unstable U6atac snRNA
eLife, 2013 Eukaryotes have two types of spliceosomes, comprised of either major (U1, U2, U4, U5, U6) or minor (U11, U12, U4atac, U6atac; <1%) snRNPs. The high conservation of minor introns, typically one amidst many major introns in several hundred genes ...

Organization and transient expression of the gene for human U11 snRNA [PDF]
, 1991 The nucleotide sequence of U11 small nuclear RNA, a minor U RNA from HeLa cells, was determined. Computer analysis of the sequence (135 residues) predicts two strong hairpin loops which are separated by seventeen nucleotides containing an Sm binding site

Knocking Down Snrnp200 Initiates Demorphogenesis of Rod Photoreceptors in Zebrafish
Journal of Ophthalmology, 2015 Purpose. The small nuclear ribonucleoprotein 200 kDa (SNRNP200) gene is a fundamental component for precursor message RNA (pre-mRNA) splicing and has been implicated in the etiology of autosomal dominant retinitis pigmentosa (adRP).
