 Context examples 

Rho proteins control actin dynamics, gene expression, membrane trafficking, growth factor signaling, and cellular transformation.

(DH Domain, NCI Thesaurus)

Rho activates cdk2 and also inhibits p21 and p27 to induce cyclin D1 and stimulate the G1 to S transition.

(G1 to S Transition Pathway, NCI Thesaurus/BIOCARTA)

This allele, which encodes rho guanine nucleotide exchange factor 7 protein, is involved in the regulation of both GTPase-mediated signaling and apoptosis.

(ARHGEF7 wt Allele, NCI Thesaurus)

Since the rho GTPases promote cytoskeletal and membrane changes associated with apoptotic cell death, the removal of the D4-GDI block through its cleavage is important for inducing apoptosis.

(D4-GDI Signaling Pathway, NCI Thesaurus/BIOCARTA)

Rho is a G protein that activates ROCK, a protein kinase.

(CCR3 Signaling Pathway, NCI Thesaurus/BIOCARTA)

Rho and ROCK regulate actin stress fiber formation and are required for eosinophil chemotaxis.

(CCR3 Signaling Pathway, NCI Thesaurus/BIOCARTA)

Rho represses p21 expression to block p21 induction by Ras and to allow Ras induced progression from G1 to S. Cells that lack p21 do not require Rho for Ras to induce cell cycle progression from G1 to S phase.
