Description:
The BAP1 gene encodes a protein called ubiquitin carboxyl-terminal hydrolase BAP1 (shortened to BAP1), which belongs to the wider family of deubiquitinating enzymes. It plays a role in diverse cellular processes, since ubiquitination can mediate protein apoptosis, modulate protein-protein interactions and regulate cellular localization of proteins, among others. BAP1 functions as a general transcriptional activator via deubiquitination of H2AK119Ub (an abundant histone modification) and other epigenetic/transcription factors (such as KLF5, DNMT1, NCoR1 and PGC1-α). BPA1 is a component of the DRED (direct repeat erythroid-definitive) repressor complex whose deubiquitinase activity maintains NCoR1 (an adaptor for the DRED complex) [GeneID: 471] at sites in the β-globin locus. DRED binds directly to DR1 elements in embryonic and fetal gene promoters and represses γ-globin transcription in definitive adult erythroid cells. BAP1 inhibition in erythroid cells (via shRNAs or CRISPR-Cas editing of HUDEP-2 cells) massively induced γ-globin synthesis, indicating that BAP1 is a candidate modulator of fetal haemoglobin (HbF) and that inhibition of BAP1 deubiquitinase activity may serve as a novel therapeutic target for γ-globin induction.
