Spliceosome assembly involves the binding and release of U4 small nuclear ribonucleoprotein.

, 1988
Splicing complexes that form a rabbit beta-globin precursor mRNA (pre-mRNA) have been analyzed for their small nuclear RNA (snRNA) content by both affinity chromatography and specific probe hybridization of replicas of native electrophoretic gels.

Circular RNA Vv‐circCOR27 modulates thermotolerance through attenuating VvHSP90.2b‐VvHsfA7a interaction in grapevine

New Phytologist, Volume 250, Issue 2, Page 988-1003, April 2026.
Summary Circular RNAs (circRNAs) are single‐stranded, covalently closed RNA molecules that arise from exon back‐splicing. The identification and function investigation of circRNAs have been comprehensively explored in plants, however, the regulatory mechanisms are largely unknown.

Dual Targeting of Mutant p53 and SNRPD2 via Engineered Exosomes Modulates Alternative Splicing to Suppress Ovarian Cancer

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Mutant p53 drives oncogenic splicing to promote the progression of ovarian cancer by partnering with the spliceosome factor SNRPD2. Therefore, it is engineered iRGD‐exosomes to co‐deliver siRNAs against both targets. This approach restored tumor‐suppressive mRNA isoforms, effectively enhanced sensitivity to cisplatin, and ultimately blocked tumor ...

In vivo analysis of NHPX reveals a novel nucleolar localization pathway involving a transient accumulation in splicing speckles [PDF]

, 2002
The NHPX protein is a nucleolar factor that binds directly to a conserved RNA target sequence found in nucleolar box C/D snoRNAs and in U4 snRNA. Using enhanced yellow fluorescent protein (EYFP)– and enhanced cyan fluorescent protein–NHPX fusions, we ...

Molecular Responses to Climate Change: How Warming and Acidification Reshape the Proteome and Phosphoproteome of the Endangered Mira Chub

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Global environmental change affects organisms, including their physiology. In freshwater ecosystems, where migration is limited, populations often rely on phenotypic plasticity to respond. While transcriptomics has been widely used to study stress responses at the molecular level, less is known about the proteome, which reflects post ...

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

Mutations in an essential U2 small nuclear RNA structure cause cold-sensitive U2 small nuclear ribonucleoprotein function by favoring competing alternative U2 RNA structures

, 1994
Mutations in stem-loop Ila of yeast U2 RNA cause cold-sensitive growth and cold-sensitive U2 small nuclear ribonucleoprotein function in vitro. Cold-sensitive U2 small nuclear RNA adopts an alternative conformation that occludes the loop and disrupts the

ATP requirement for Prp5p function is determined by Cus2p and the structure of U2 small nuclear RNA [PDF]

, 2003
Stable addition of U2 small nuclear ribonucleoprotein (snRNP) to form the prespliceosome is the first ATP-dependent step in splicing, and it requires the DEXD/H box ATPase Prp5p.
