Summary: Enables G-protein beta-subunit binding activity; GTPase activity; and enzyme activator activity. Involved in several processes, including cytoskeleton organization; regulation of exocyst localization; and regulation of mitotic cytokinetic process. Located in several cellular components, including cellular bud tip; fungal-type vacuole membrane; and incipient cellular bud site. Part of 1,3-beta-D-glucan synthase complex. Used to study ulcerative colitis. Human ortholog(s) of this gene implicated in breast carcinoma. Orthologous to human RHOA (ras homolog family member A); RHOB (ras homolog family member B); and RHOC (ras homolog family member C). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Authors propose that Rho1 and Pkc1 coordinate septin ring assembly with membrane and cell wall remodeling partly by controlling Syp1 residence at the bud neck.
Title: Rho1- and Pkc1-dependent phosphorylation of the F-BAR protein Syp1 contributes to septin ring assembly.
These results suggested that the tumour suppressor homologue SRO7/SRO77 regulated cell proliferation and yeast colony development via the Rho1-Tor1 pathway.
Title: Sro7 and Sro77, the yeast homologues of the Drosophila lethal giant larvae (Lgl), regulate cell proliferation via the Rho1-Tor1 pathway.
the Rho1p-eEF1A complex acts to spatially localize a pool of eEF1A to vacuoles where it can readily organize F-actin.
Title: Yeast translation elongation factor-1A binds vacuole-localized Rho1p to facilitate membrane integrity through F-actin remodeling.
The signaling network of Rho1 extends into many TORC1-dependent processes and sheds light on how yeast cells coordinate polarized spatial expansion with mass increase.
Title: TOR under stress: targeting TORC1 by Rho1 GTPase.
synthesis of the cell wall through partitioning glucose to the periphery and the formation of the signaling complex with Rom2 and Ssd1 to promote Rho1-dependent polarized cell growth.
Title: PAS kinase promotes cell survival and growth through activation of Rho1.
TOR complex 1 acts both upstream and downstream of Rho1 GTPase, unveiling a mechanism that integrates stress and nutrient signals to coordinate Rho1-mediated spatial expansion and TORC1-dependent mass increase.
Title: The TOR complex 1 is a direct target of Rho1 GTPase.
The result reveal the existence of a second pathway for endocytosis in yeast, which suggests similarities with the RhoA-dependent endocytic pathways of mammalian cells.
Title: Existence of a novel clathrin-independent endocytic pathway in yeast that depends on Rho1 and formin.
Rho1 protects yeast cells from oxidative stress by regulating multiple downstream targets including Ycf1.
Title: The Rho1 GTPase acts together with a vacuolar glutathione S-conjugate transporter to protect yeast cells from oxidative stress.
Mtl1 has an essential role in signaling oxidative stress and quiescence to the CWI pathway and to the general stress response through Rho1 and the inhibition of either the TOR1 or RAS2 functions
Title: Mtl1 is required to activate general stress response through Tor1 and Ras2 inhibition under conditions of glucose starvation and oxidative stress.
These results define unique activation mechanisms for Cdc42p and Rho1p, which may be linked to the vacuole membrane fusion mechanism.
Title: Cdc42p and Rho1p are sequentially activated and mechanistically linked to vacuole membrane fusion.
