Rho Factor: Transcription Termination in Four Steps [PDF]

open access: yesCurrent Biology, 2003
Rho factor is a hexameric ring-shaped helicase which terminates transcription in Escherichia coli. Two recent crystal structures of Rho in complex with nucleic acid reveal how this helicase ring loads onto mRNA and encircles it.

Rho-dependent transcription termination proceeds via three routes

open access: yesNature Communications, 2022
Rho is a general transcription termination factor in bacteria. Here, Song et al. use single-molecule fluorescence assays to provide evidence that Rho-mediated transcription termination can occur via three kinetically different routes.

Spatiotemporal recruitment of RhoGTPase protein GRAF inhibits actomyosin ring constriction in Drosophila cellularization

open access: yeseLife, 2021
Actomyosin contractility is regulated by Rho-GTP in cell migration, cytokinesis and morphogenesis in embryo development. Whereas Rho activation by Rho-GTP exchange factor (GEF), RhoGEF2, is well known in actomyosin contractility during cytokinesis at the

The Y-box factor ZONAB/DbpA associates with GEF-H1/Lfc and mediates Rho-stimulated transcription [PDF]

open access: yes, 2009
Epithelial tight junctions recruit different types of signalling proteins that regulate cell proliferation and differentiation. Little is known about how such proteins interact functionally and biochemically with each other.

Computer vision profiling of neurite outgrowth mordphodynamics reveals spatio-temporal modularity of Rho GTPase signaling [PDF]

open access: yes, 2014
Neurite outgrowth is essential to build the neuronal processes that produce axons and dendrites that connect the adult brain. In cultured cells, the neurite outgrowth process is highly dynamic, and consists of a series of repetitive morphogenetic sub ...

Obscurin Rho GEF domains are phosphorylated by MST-family kinases but do not exhibit nucleotide exchange factor activity towards Rho GTPases in vitro.

open access: yesPLoS ONE, 2023
Obscurin is a giant muscle protein (>800 kDa) featuring multiple signalling domains, including an SH3-DH-PH domain triplet from the Trio-subfamily of guanosine nucleotide exchange factors (GEFs).

Rho-mediated transcriptional control.

open access: yes, 2023
Examples of expression profiles of B. subtilis WT, Rho+ and Δrho strains at two loci (A and B) as measured by RNAseq in exponential (middle panel) and stationary (bottom panel) growth phases for both strands of the genome (+ and -).

Role of contractile prostaglandins and Rho-kinase in growth factor-induced airway smooth muscle contraction

open access: yesRespiratory Research, 2005
Background In addition to their proliferative and differentiating effects, several growth factors are capable of inducing a sustained airway smooth muscle (ASM) contraction.

Principles that govern competition or co-existence in Rho-GTPase driven polarization. [PDF]

open access: yesPLoS Computational Biology, 2018
Rho-GTPases are master regulators of polarity establishment and cell morphology. Positive feedback enables concentration of Rho-GTPases into clusters at the cell cortex, from where they regulate the cytoskeleton.
