This entry represents the ubiquitin-like domain (UBL) found in ZFAND1 proteins. The domain adopts a beta-grasp fold similar to ubiquitin and other UBLs, but contains an additional N-terminal helix. The UBL domain is the primary interaction site with p97/VCP and is essential for stress granule clearance. The domain shows limited sequence identity (<18%) with other UBLs despite structural similarity. Crystal and NMR structures reveal that the N-terminal helix adopts different conformations in solution versus crystal states [1].
