Involved in the DNA damage response pathway by contributing to the maintenance of chromatin architecture. Recruited to the vicinity of DNA breaks by TP53BP1 and plays an accessory role to facilitate damage-induced chromatin changes and promoting chromatin relaxation. Required for efficient DNA repair and cell survival following DNA damage.
Belongs to the MUM1 family. Contains 1 PWWP domain.
The PWWP domain mediates the interaction with nucleosomes.
Phosphorylated upon DNA damage, probably by ATM or ATR.
Nucleus. Recuited to DNA damage sites via its interaction with the BRCT domain of TP53BP1.
