Urm1 is a ubiquitin related protein that modifies proteins in the yeast ubiquitin-like pathway urmylation [1]. Structural comparisons and phylogenetic analysis of the ubiquitin superfamily has indicated that Urm1 has the most conserved structural and sequence features of the common ancestor of the entire superfamily [2].
