SP-RING for SUMO: new functions bloom for a ubiquitin-like protein.
SUMO is covalently linked to a variety of cellular proteins. Three groups now describe related E3-like factors that enhance transfer of SUMO to specific proteins. This family of factors includes proteins important for chromosome condensation, signal transduction, and ion channel biogenesis.
