Ubiquitin (Ub) regulates numerous cellular processes through covalent attachment to other proteins in the forms of poly- and mono-ubiquitination. A recent study in yeast shows that ubiquitin controls TORC1 through a noncovalent binding with Kog1, a regulatory subunit of TORC1. The binding stabilizes Kog1 and prevents its degradation under stress conditions. This finding unveils a novel role of Ub in TORC1 function and implicates a unique mechanism that attributes the action of Ub in cell signaling.
