SUGP1 loss drives SF3B1 hotspot mutant missplicing in cancer
Cancer-Causing Mutations in SF3B1 Alter Splicing by Disrupting Interaction with SUGP1
Genetic alterations of SUGP1 mimic mutant-SF3B1 splice pattern in lung adenocarcinoma and other cancers
The purpose of the project is to identify proteins binding differentially to the human specific spliceosomal protein SUGP1 in the context of point mutations to its G-patch domain. SUGP1 wt and mutant (G603N or L570E) C-terminally tagged with mini-Turbo-NLS was overexpressed for 48 h in HEK293T cell...

SF3B1 is the most frequently mutated splicing factor in cancer. Such mutations cause missplicing by promoting aberrant 3' splice site usage; however, how this occurs mechanistically remains controversial. To address this issue, we employed a computational screen of 600 splicing-related proteins to i...

SF3B1, which encodes an essential spliceosomal protein, is frequently mutated in myelodysplastic syndromes (MDS) and many cancers. However, the defect of mutant SF3B1 is unknown. Here, we analyzed RNA-sequencing data from MDS patients and confirmed that SF3B1 mutants use aberrant 3' splice sites. To...
