Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

CUS1, a suppressor of cold-sensitive U2 snRNA mutations, is a novel yeast splicing factor homologous to human SAP 145.

Wells SE, Neville M, Haynes M, Wang J, Igel H, Ares M

The function of U2 snRNA in splicing is mediated by the proteins of the U2 small nuclear ribonucleoprotein. To identify proteins that influence the function of U2 snRNA we carried out a screen for mutations in Saccharomyces cerevisiae that suppress the cold-sensitive growth defect of a mutation in U2 stem loop IIa, a structure important for the stable association of ...
