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.

Genetic interactions of hypomorphic mutations in the m7G cap-binding pocket of yeast nuclear cap binding complex: An essential role for Cbc2 in meiosis via splicing of MER3 pre-mRNA.

Nuclear cap binding protein complex (CBC) is a heterodimer of a small subunit (Cbc2 in yeast) that binds the m(7)G cap and a large subunit (Sto1 in yeast) that interacts with karyopherins. In order to probe the role of cap recognition in yeast CBC function, we introduced alanine mutations (Y24A, F91A, D120A, D122A, R129A, and R133A) and N-terminal deletions (NΔ21 ... [more]
