RAS2

CTN5, CYR3, GLC5, TSL7, Ras family GTPase RAS2, L000001583, YNL098C
GTP-binding protein; regulates nitrogen starvation response, sporulation, and filamentous growth; farnesylation and palmitoylation required for activity and localization to plasma membrane; homolog of mammalian Ras proto-oncogenes; RAS2 has a paralog, RAS1, that arose from the whole genome duplication

Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Publication

The C-terminal domain of the largest subunit of RNA polymerase II is required for stationary phase entry and functionally interacts with the Ras/PKA signaling pathway.

Howard SC, Budovskaya YV, Chang YW, Herman PK

The Saccharomyces cerevisiae Ras proteins control cell growth by regulating the activity of the cAMP-dependent protein kinase (PKA). In this study, a genetic approach was used to identify cellular processes that were regulated by Ras/PKA signaling activity. Interestingly, we found that mutations affecting the C-terminal domain (CTD), of Rpb1p, the largest subunit of RNA polymerase II, were very sensitive to ... [more]
