GPN2

YOR262W
Putative GTPase with a role in biogenesis of RNA pol II and polIII; may be involved in assembly of RNA polymerases II and III and in their transport into the nucleus; contains a Gly-Pro-Asn motif in the G domain; similar to Npa3p and Gpn3p; highly conserved across species and homologous to human gene GPN2/ATPBD1B; required for establishment of sister chromatid cohesion

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Biogenesis of RNA Polymerases II and III Requires the Conserved GPN small GTPases in Saccharomyces cerevisiae.

Minaker SW, Filiatrault MC, Ben-Aroya S, Hieter P, Stirling PC

The GPN proteins are a poorly-characterized and deeply evolutionarily conserved family of three paralogous small GTPases, Gpn1, 2 and 3. The founding member, GPN1/NPA3/XAB1, is proposed to function in nuclear import of RNA polymerase II along with a recently described protein called Iwr1. Here we show that the previously uncharacterized protein Gpn2 binds both Gpn3 and Npa3/Gpn1, and that temperature-sensitive ... [more]
