"Numerous studies have demonstrated that truncated ASXL1 mutants, including the ASXL1 fragment containing amino acids 1–587, promote myeloid transformation by forming a stable polycomb-repressive deubiquitinase (PR-DUB) complex with BAP1, enhancing BAP1 deubiquitinase (DUB) activity [ xref , xref , xref ]."

"The interaction with BRCA1 and BARD1 form a tumor suppressor heterodimeric complex. [ xref ] BAP1 regulates cell proliferation and interacts with histone-modifying complexes during cell division. [ xref , xref ] BAP1 also forms the Polycomb group repressive deubiquitinase complex (PR-DUB) through interaction with ASXL1, which is involved several developmental processes. [ xref ] Because of this functional complexity, BAP1 germline mutations predispose individuals to the aggressive tumor phenotypes."
