Biological context of URM1

 

Associations of URM1 with chemical compounds

  • Urm1 is conjugated to target proteins, which requires the C-terminal glycine of Urm1 [9].
  • Urm1 and Uba4 show similarity to prokaryotic proteins essential for molybdopterin and thiamin biosynthesis, although the Urm1 system is not involved in these pathways [9].
  • SUMO (small ubiquitin-related modifier) modulates protein structure and function by covalently binding to the lysine side chains of the target proteins [10].
 

Other interactions of URM1

  • At the first step of this reaction, Urm1 forms a thioester with a novel E1-like protein, Uba4 [9].
  • Simultaneous loss of Urm1p and Cla4p, a p21-activated kinase that functions in budding, is lethal [11].
  • Moreover, treatment of cells with thiol-specific oxidants affects the abundance of Ahp1p-Urm1p conjugates [8].
  • In S phase, even in the absence of exogenous DNA damage, yeast PCNA can be alternatively modified by the small ubiquitin-related modifier protein SUMO; however the consequences of this remain controversial [12].
