Protein: Proteasome activator BLM10 (Bleomycin resistance protein BLM10) (P43583)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Associated component of the proteasome that specifically recognizes acetylated histones and promotes ATP- and ubiquitin-independent degradation of core histones during DNA damage response. Recognizes and binds acetylated histones via its bromodomain-like (BRDL) region and activates the proteasome by opening the gated channel for substrate entry. Binds to the core proteasome via its C-terminus, which occupies the same binding sites as the proteasomal ATPases, opening the closed structure of the proteasome via an active gating mechanism. Involved in DNA damage response in somatic cells: binds to acetylated histones and promotes degradation of histones following DNA double-strand breaks.
Subcellular location: Nucleus. Cytoplasm.
