MMS2
E2 ubiquitin-conjugating protein MMS2, L000004015, YGL087C
Ubiquitin-conjugating enzyme variant; involved in error-free postreplication repair; forms a heteromeric complex with Ubc13p, an active ubiquitin-conjugating enzyme; cooperates with chromatin-associated RING finger proteins, Rad18p and Rad5p; protein abundance increases in response to DNA replication stress

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Pol32 is required for Pol zeta-dependent translesion synthesis and prevents double-strand breaks at the replication fork.
POL32 encodes a non-essential subunit of Poldelta and plays a role in Poldelta processivity and DNA repair. In order to understand how Pol32 is involved in these processes, we performed extensive genetic analysis and demonstrated that POL32 is required for Polzeta-mediated translesion synthesis, but not for Poleta-mediated activity. Unlike Polzeta, inactivation of Pol32 does not result in decreased spontaneous mutagenesis, ... [more]
