What's a GeneRIF?

Replacement of proline with leucine at position 123 induces a switch from the preferential addition of SUMO to lysine residues in unstructured sites to acceptor lysines embedded in secondary structures. This causes alterations in SUMO chain linkages.
Title: UBC9 Mutant Reveals the Impact of Protein Dynamics on Substrate Selectivity and SUMO Chain Linkages.
Ubc9 sumoylation is a key event for meiotic synaptonemal complex formation. SUMO Ubc9 enhances catalysis by binding and orienting donor SUMO charged Ubc9.
Title: Ubc9 sumoylation controls SUMO chain formation and meiotic synapsis in Saccharomyces cerevisiae.
The crystal structure of sumoylated Ubc9 demonstrates how the newly created binding interface can provide a gain in affinity otherwise provided by E3 ligases.
Title: Ubc9 sumoylation regulates SUMO target discrimination.
These findings establish a functional interaction between N-terminal and substrate-binding domains of Ubc9 and distinguish the activities of E3 ligases Siz1 and Siz2 in regulating cellular responses to genotoxic stress.
Title: Distinct functional domains of Ubc9 dictate cell survival and resistance to genotoxic stress.
