RHO4

Rho family GTPase RHO4, L000001633, YKR055W
Non-essential small GTPase; member of the Rho/Rac subfamily of Ras-like proteins; likely to be involved in the establishment of cell polarity; has long N-terminal extension that plays an important role in Rho4p function and is shared with Rho4 homologs in other yeasts and filamentous fungi

BNI1

PPF3, SHE5, formin BNI1, L000000190, YNL271C
Formin; polarisome component; nucleates the formation of linear actin filaments, involved in cell processes such as budding and mitotic spindle orientation which require the formation of polarized actin cables, functionally redundant with BNR1
Saccharomyces cerevisiae (S288c)

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Formin-dependent actin assembly is regulated by distinct modes of Rho signaling in yeast.

Dong Y, Pruyne D, Bretscher A

Formins are actin filament nucleators regulated by Rho-GTPases. In budding yeast, the formins Bni1p and Bnr1p direct the assembly of actin cables, which guide polarized secretion and growth. From the six yeast Rho proteins (Cdc42p and Rho1-5p), we have determined that four participate in the regulation of formin activity. We show that the essential function of Rho3p and Rho4p is ...
