"In addition to TFs, SLC7A11 transcription is also repressed by BRCA1-associated protein 1 (BAP1) – a major component of a deubiquitinase (DUB) complex which catalyzes deubiquitination of histone 2 A (H2A) associated with the SLC7A11 promoter.96 Not surprisingly, BAP1 promotes ferroptosis in a DUB-dependent manner."

"OTUB1 overexpression is frequently found in various human cancers, which maintains high expression of SLC7A11 in cancer cells by posttranslational regulation of OTUB1.De-repression of SLC7A11 also promotes tumor development partly via inhibiting ferroptosis, e.g., genetic mutations or deletions of tumor suppressor p53 or BAP1."
