BRCC36 hydrolyzes lysine linked ubiquitin chains as part of macromolecular complexes that participate in either interferon signalling or DNA-damage recognition. The domain consists of 2 non canonical helices. The domain interacts hydrophobically with helices alpha 4 and alpha 5 of KIAA0157 in the form of a coiled coil helical bundle. This interaction helps establish the association of BRCC36 with KIAA0157, a pseudo-DUB MPN- protein that is essential for the activity of BRCC36 [1].

This domain is known as the MPN domain [3] and PAD-1-like domain [4], JABP1 domain [5] or JAMM domain [7]. These are metalloenzymes that function as the ubiquitin isopeptidase/ deubiquitinase in the ubiquitin-based signalling and protein turnover pathways in eukaryotes [7]. Versions of the domain in prokaryotic cognates of the ubiquitin-modification pathway are shown to have a similar role, and the archaeal protein from Haloferax volcanii is found to cleave ubiquitin-like small archaeal modifier proteins (SAMP1/2) from protein conjugates [8,9].
