U2AF1 mutations alter sequence specificity of pre-mRNA binding and splicing

T Okeyo-Owuor, BS White, R Chatrikhi, DR Mohan… - Leukemia, 2015 - nature.com
We previously identified missense mutations in the U2AF1 splicing factor affecting codons
S34 (S34F and S34Y) or Q157 (Q157R and Q157P) in 11% of the patients with de novo …

[HTML][HTML] Wild-type U2AF1 antagonizes the splicing program characteristic of U2AF1-mutant tumors and is required for cell survival

DL Fei, H Motowski, R Chatrikhi, S Prasad, J Yu… - PLoS …, 2016 - journals.plos.org
We have asked how the common S34F mutation in the splicing factor U2AF1 regulates
alternative splicing in lung cancer, and why wild-type U2AF1 is retained in cancers with this …
