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.

Yrb2p, a Nup2p-related yeast protein, has a functional overlap with Rna1p, a yeast Ran-GTPase-activating protein.

The Ran-GTPase cycle is important for nucleus-cytosol exchange of macromolecules and other nuclear processes. We employed the two-hybrid method to identify proteins interacting with Ran and the Ran GTP/GDP exchange factor. Using PRP20, encoding the Ran GTP/GDP exchange factor, we identified YRB1, previously identified as a protein able to interact with human Ran GTP/GDP exchange factor RCC1 in the two-hybrid ...
