A potential proteasome-interacting motif within the ubiquitin-like domain of parkin and other proteins

Trends Biochem Sci. 2003 Jun;28(6):280-3. doi: 10.1016/S0968-0004(03)00092-6.

Abstract

Parkin and other unrelated proteins contain a ubiquitin-like domain (UbLD). This article describes a motif that might be important in the interaction of UbLD-containing proteins (UbLPs) with the proteasome. The proteasome-interacting motif, which is conserved in a subset of UbLPs, such as parkin, Rad23 and several transcription factors, is likely to enable the UbLPs to form a complex with the proteasome for proteolysis or the recently discovered non-proteolytic functions of the proteasome.
