Abstract
This entry represents a group of plant UBX domain-containing proteins, including AtPUX1 from Arabidopsis. AtPUX1 regulates the hexameric structure and ATPase activity of AtCDC48, an essential AAA-ATPase chaperone that functions in numerous diverse cellular activities [ 1 ].
The UBX domain is comprised of ~80 amino acids and shares common secondary structure organisation with ubiquitin. In contrast to ubiquitin, UBX domains lack the C-terminal glycine motif necessary for covalent coupling to target proteins [ 2 ].
