Myb-like, SWIRM and MPN domain-containing protein 1; Metalloprotease that specifically deubiquitinates monoubiquitinated histone H2A, a specific tag for epigenetic transcriptional repression, thereby acting as a coactivator. Preferentially deubiquitinates monoubiquitinated H2A in hyperacetylated nucleosomes. Deubiquitination of histone H2A leads to facilitate the phosphorylation and dissociation of histone H1 from the nucleosome. Acts as a coactivator by participating in the initiation and elongation steps of androgen receptor (AR)-induced gene activation; Myb/SANT domain containing
Synonyms: MYSM1, MYSM1p, hMYSM1, Q5VVJ2, KIAA1915 ...
