This is the C-terminal domain found in eukaryotic UCH37 proteins (also known as Ubiquitin carboxyl-terminal hydrolase isozyme L5, UCHL5). UCH37 is a subunit of two complexes: INO80, which performs ATP-dependent sliding of nucleosomes for transcriptional regulation and DNA repair, and the 26S proteasome, which performs ATP-dependent proteolysis of polyubiquitylated proteins in the cytosol and nucleus. Recruitment to the proteasome is mediated by the C-terminal domain of RPN13 (also known as ADRM1). Recruitment to INO80 is mediated by the N-terminal domain of NFRKB. Structural and biochemical analysis reveal that RPN13 and NFRKB make similar interactions with the UCH37 C-terminal domain but have very different interactions with the catalytic UCH domain that are activating in the case of RPN13 and highly inhibitory in the case of NFRKB [3].

A conserved alpha helical domain with a characteristic LXXLL motif [1] [2]. The LXXLL motif is detected in diverse transcription factors, coactivators and corepressors and is implicated in mediating interactions between them [3]. The ASXH domain is found in animals, fungi and plants [4] and is predicted to play a role in mediating contact between transcription factors and chromatin-associated complexes. In Drosophila Asx and Human ASXL1, the ASXH domain is predicted to mediate interactions with the Calypso and BAP1 deubiquitinases (DUBs) which further belong to the UCHL5/UCH37 clade of DUBs [4].
