DNA6, UBC3, SCF E2 ubiquitin-protein ligase catalytic subunit CDC34, L000000271, YDR054C
Ubiquitin-conjugating enzyme (E2); catalytic subunit of SCF ubiquitin-protein ligase complex (together with Skp1p, Rbx1p, Cdc53p, and an F-box protein) that regulates cell cycle progression by targeting key substrates for degradation; protein abundance increases in response to DNA replication stress

LAG2

ECM36, L000003402, YOL025W
Protein that negatively regulates the SCF E3-ubiquitin ligase; regulates by interacting with and preventing neddyation of the cullin subunit, Cdc53p; longevity determinant that is preferentially expressed in young cells; similar to mammalian Cand1

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Publication

A longevity protein, Lag2, interacts with SCF complex and regulates SCF function.

Liu Y, Mimura S, Kishi T, Kamura T

SCF-type E3-ubiquitin ligases control numerous cellular processes through the ubiquitin-proteasome pathway. However, the regulation of SCF function remains largely uncharacterized. Here, we report a novel SCF complex-interacting protein, Lag2, in Saccharomyces cerevisiae. Lag2 interacts with the SCF complex under physiological conditions. Lag2 negatively controls the ubiquitylation activities of SCF E3 ligase by interrupting the association of Cdc34 to SCF complex. ... [more]
