Somatic Mutational Landscape of Splicing Factor Genes and Their Functional Consequences across 33 Cancer Types [PDF]

open access: yesCell Reports, 2018
Summary: Hotspot mutations in splicing factor genes have been recently reported at high frequency in hematological malignancies, suggesting the importance of RNA splicing in cancer.

Exon inclusion signatures enable accurate estimation of splicing factor activity [PDF]

open access: yesNature Communications
Splicing factors control exon inclusion in messenger RNAs, shaping transcriptome and proteome diversity. Their catalytic activity is regulated by multiple layers, making single-omic measurements on their own fall short in identifying which splicing ...

Split-APEX implicates splicing factor SRSF1 and splicing helicases in ribosomal biogenesis [PDF]

open access: yesFrontiers in Molecular Biosciences
SR proteins are RNA-binding proteins with one or two RNA recognition motif (RRM)-type RNA-binding domains and a C-terminal region rich in arginine-serine dipeptides. They function in cellular processes ranging from transcription to translation.

Lamin B1 regulates RNA splicing factor expression by modulating the spatial positioning and chromatin interactions of the ETS1 gene locus [PDF]

open access: yesAnimal Cells and Systems
Lamin B1, a crucial component of the nuclear lamina, plays a pivotal role in chromatin organization and transcriptional regulation in eukaryotic cells. While recent studies have highlighted the connection between Lamin B1 and RNA splicing regulation, the

Serine and arginine rich splicing factor 1: a potential target for neuroprotection and other diseases

open access: yesNeural Regeneration Research, 2023
Alternative splicing is the process of producing variably spliced mRNAs by choosing distinct combinations of splice sites within a messenger RNA precursor.

The mutation in splicing factor genes correlates with unfavorable prognosis, genomic instability, anti-tumor immunosuppression and increased immunotherapy response in pan-cancer

open access: yesFrontiers in Cell and Developmental Biology, 2023
Splicing abnormality resulting from somatic mutations in key splicing factor genes (SFG) has been detected in various cancers. Hence, an in-depth study of splicing factor genes mutations’ impact on pan-cancer is meaningful.

SON drives oncogenic RNA splicing in glioblastoma by regulating PTBP1/PTBP2 switching and RBFOX2 activity

open access: yesNature Communications, 2021
Splicing factor PTBP1 is reported to promote oncogenic functions in glioblastoma (GBM). Here the authors show splicing factor SON upregulates PTBP1 expression while supresses its paralog PTBP2 through alternative splicing and the inhibition of SON ...

RNA-Binding Proteins Hold Key Roles in Function, Dysfunction, and Disease

open access: yesBiology, 2021
RNA-binding proteins (RBPs) are multi-faceted proteins in the regulation of RNA or its RNA splicing, localisation, stability, and translation. Amassing proof from many recent and dedicated studies reinforces the perception of RBPs exerting control ...

Comprehensive Analysis of Splicing Factor and Alternative Splicing Event to Construct Subtype-Specific Prognosis-Predicting Models for Breast Cancer

open access: yesFrontiers in Genetics, 2021
Recent evidence suggests that splicing factors (SFs) and alternative splicing (AS) play important roles in cancer progression. We constructed four SF-risk-models using 12 survival-related SFs.

Oncogenic KRAS alters splicing factor phosphorylation and alternative splicing in lung cancer

open access: yesBMC Cancer, 2022
Background Alternative RNA splicing is widely dysregulated in cancers including lung adenocarcinoma, where aberrant splicing events are frequently caused by somatic splice site mutations or somatic mutations of splicing factor genes.
