Epistasis analysis of the <i>ufd1ΔCt</i>^{<i>213-342</i>} mutation with mutations in DNA repair or STUbL pathway.

<p>(A, B, C) 10-fold serial dilutions of the indicated strains were spotted onto YES plates with or without DNA-damaging agents as indicated, or onto plates subsequently exposed to UV irradiation. (A) Epistatic relationship of <i>ufd1ΔCt</i>^{<i>213-342</i>} with <i>pli1Δ</i> indicates non-overlapping functions of Ufd1 and the STUbL pathway. (B) Negative genetic interactions between <i>ufd1ΔCt</i>^{<i>213-342</i>} and mutations of HR repair proteins. (C) Partial suppression of <i>ufd1ΔCt</i>^{<i>213-342</i>} CPT sensitivity by <i>rhp18Δ</i> and <i>ubc13Δ</i>.
