Variant-specific SF3B1 mutations drive distinct splicing and mitochondrial dysfunction in myelodysplastic neoplasms [PDF]
Background SF3B1 spliceosome mutations are among the most common genetic lesions in myelodysplastic neoplasms (MDS). The canonical hotspot K700E variant is generally associated with a favorable prognosis, whereas the impact of other recurrent variants is

Modulation of splicing factors SF3B1 and SRSF1 by polypurine reverse Hoogsteen hairpins affects the splicing pattern of estrogen receptor α in breast cancer cells [PDF]
Multiple mRNA splice variants for the human estrogen receptor α (ERα) with one or more skipped exons have been identified, and some encode isoforms with modified functions compared with the wild-type 66 kDa protein.

SF3B1 thermostability as an assay for splicing inhibitor interactions [PDF]
The spliceosome protein, SF3B1, is associated with U2 snRNP during early spliceosome assembly for pre-mRNA splicing. Frequent somatic mutations in SF3B1 observed in cancer necessitates the characterization of its role in identifying the branchpoint adenosine of introns.

Phosphorylation of SF3B1 by CDK11 orchestrates spliceosome activation via SNIP1-dependent RES complex recruitment [PDF]
Splicing Factor 3b Subunit 1 (SF3B1), a core component of the spliceosome, undergoes dynamic phosphorylation and dephosphorylation during the splicing cycle to regulate pre-mRNA splicing. Twenty-eight threonine/proline repeats are phosphorylated by CDK11

Concurrent Mutations in SF3B1 and PHF6 in Myeloid Neoplasms
It has been reported that gene mutations in SF3B1 and PHF6 are mutually exclusive. However, this observation has never been rigorously assessed. We report the clinicopathologic and molecular genetic features of 21 cases of myeloid neoplasms with double mutations in SF3B1 and PHF6, including 9 (43%) with myelodysplastic syndrome, 5 (24%) with acute ...

The Impact of SF3B1 Mutations on the Tumor Microenvironment and Response to Immunotherapy
Cancer genomes shape the immune landscape within the tumor microenvironment (TME), thereby influencing host antitumor immunity. Identifying somatic mutations that modulate the TME is critical for selecting patients most likely to benefit from ...

Phase Separation of SF3B1 Serves as a Critical Post-Transcriptional Regulator During Early Mouse Embryogenesis. [PDF]
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

De novo variants in the splicing factor gene SF3B1 are associated with neurodevelopmental disorders [PDF]
SF3B1 is an essential and ubiquitous splicing factor that plays a pivotal role in the early steps of pre-mRNA splicing. Recurrent somatic missense mutations in SF3B1 are frequent in cancers, but no constitutional variant has been reported so far.

Distinct routes of clonal progression in SF3B1-mutant myelodysplastic syndromes
: Myelodysplastic syndromes (MDS) are clonal stem cell disorders driven by heterogeneous genetic alterations leading to variable clinical course. MDS with splicing factor SF3B1 mutations is a distinct subtype with a favorable outcome.
