Schematic representation of the four human Josephin-domain-containing proteins. Josephin domains are shown in light gray, the ubiquitin-interacting motifs (UIM) are shown in dark gray, and the polyglutamine (polyQ) repeat regions are shown as cross-hatched. The sizes of the ubiquitin-interacting motifs and polyQ regions are not shown to scale. The scale at the top shows length in amino acids.
