PSMD14 promotes hepatocellular carcinoma cell proliferation through E2F4-dependent PHF5A transcription and alternative splicing.
Dysregulation of the ubiquitin-proteasome system contributes to hepatocellular carcinoma (HCC), but how deubiquitination is linked to transcriptional regulation and alternative splicing remains unclear. In this study, proteomic analysis identified E2F4 as a PSMD14-interacting protein. Co-immunoprecipitation and ubiquit...
