===THE CRYSTAL STRUCTURE OF THE COMPLEX BETWEEN THE UBA AND UBL DOMAINS OF DSK2===

~~==Overview==~~

<!--

The ~~yeast proteins Dsk2 and Rad23 belong~~ to ~~a family of proteins that contain an N-terminal ubiquitin-like domain (UBL) and a C-terminal ubiquitin-associated domain~~ (~~UBA). Both Dsk2 and Rad23 function~~ as adaptors to target ubiquitin-labelled proteins to the proteasome through recognition of polyubiquitin (four or more K48-linked ubiquitins) by their UBA domains and to the yeast proteasomal subunit Rpn1 by their UBL domains. ~~The crystal structures of the Dsk2 UBL domain, the Dsk2 UBA domain and the Dsk2 UBA-UBL complex are reported~~. ~~In the crystal~~, the ~~Dsk2 UBA domains associate through electrostatic interactions to form ninefold helical ribbons that leave the ubiquitin-binding surface exposed~~. ~~The UBA~~-~~UBL complex explains the reduced affinity of the UBA domain for UBL compared with ubiquitin and has implications for the regulation of Dsk2 adaptor function during ubiquitin~~-~~mediated proteasomal targeting. A model is discussed in which two or more Dsk2 UBA molecules may selectively bind to K48-linked polyubiquitin.~~
