CC   -!- FUNCTION: May function as a protein modifier covalently attached to
CC       lysine residues of substrate proteins. This may serve to target the
CC       modified proteins for degradation by proteasomes.
CC       {ECO:0000305|PubMed:28087277}.
CC   -!- SIMILARITY: Belongs to the ubiquitin-like protein UBact family.
CC       {ECO:0000255|HAMAP-Rule:MF_02133}.
