The Conserved RNA Binding Cyclophilin, Rct1, Regulates Small RNA Biogenesis and Splicing Independent of Heterochromatin Assembly

Cell Reports, 2017
Summary: RNAi factors and their catalytic activities are essential for heterochromatin assembly in S. pombe. This has led to the idea that siRNAs can promote H3K9 methylation by recruiting the cryptic loci regulator complex (CLRC), also known as ...

FMRP deficiency leads to multifactorial dysregulation of splicing and mislocalization of MBNL1 to the cytoplasm.

PLoS Biology, 2023
Fragile X syndrome (FXS) is a neurodevelopmental disorder that is often modeled in Fmr1 knockout mice where the RNA-binding protein FMRP is absent. Here, we show that in Fmr1-deficient mice, RNA mis-splicing occurs in several brain regions and peripheral

Identification of an RNA Binding Specificity for the Potential Splicing Factor TLS [PDF]

Journal of Biological Chemistry, 2001
The TLS/FUS gene is involved in a recurrent chromosomal translocation in human myxoid liposarcomas. We previously reported that TLS is a potential splicing regulator able to modulate the 5'-splice site selection in an E1A pre-mRNA. Using an in vitro selection procedure, we investigated whether TLS exhibits a specificity with regard to RNA recognition ...

Pre-mRNA Splicing in Plants: In Vivo Functions of RNA-Binding Proteins Implicated in the Splicing Process

Biomolecules, 2015
Alternative pre-messenger RNA splicing in higher plants emerges as an important layer of regulation upon exposure to exogenous and endogenous cues. Accordingly, mutants defective in RNA-binding proteins predicted to function in the splicing process show ...

Interaction of hnRNPA1/A2 and DAZAP1 with an Alu-derived intronic splicing enhancer regulates ATM aberrant splicing. [PDF]

PLoS ONE, 2011
We have previously identified an Alu-derived Intronic Splicing enhancer (ISE) in the Ataxia Teleangectasia Mutated gene (ATM) that facilitates intron pre-mRNA processing and leads to the inclusion of a cryptic exon in the final mRNA transcript.

L4-33K, an Adenovirus-encoded Alternative RNA Splicing Factor [PDF]

Journal of Biological Chemistry, 2006
Splicing of the adenovirus IIIa mRNA is subjected to a strict temporal regulation during virus infection such that efficient IIIa 3' splice site usage is confined to the late phase of the infectious cycle. Here we show that the adenovirus L4-33K protein functions as a virus-encoded RNA splicing factor that preferentially activates splicing of ...

Role of the Constitutive Splicing Factors U2AF65 and SAP49 in Suboptimal RNA Splicing of Novel Retroviral Mutants [PDF]

Journal of Biological Chemistry, 1998
Retroviruses display a unique form of alternative splicing in which both spliced and unspliced RNAs accumulate in the cytoplasm. Simple retroviruses, such as avian sarcoma virus, do not encode regulatory proteins that affect splicing; this process is controlled solely through interactions between the viral RNA and the host cell splicing machinery ...

Transcriptome-wide analysis of alternative RNA splicing events in Epstein-Barr virus-associated gastric carcinomas.

PLoS ONE, 2017
Multiple human diseases including cancer have been associated with a dysregulation in RNA splicing patterns. In the current study, modifications to the global RNA splicing landscape of cellular genes were investigated in the context of Epstein-Barr virus-

Dual function of SF3B2 on chromatin and RNA to regulate transcription in head and neck squamous cell carcinoma

Cell & Bioscience, 2022
RNA is spliced concomitantly with transcription and the process is organized by RNA splicing factors, transcriptional regulators, and chromatin regulators. RNA is spliced in close proximity to transcription machinery. Hence, some RNA splicing factors may
