Differential regulation of adhesion complex turnover by ROCK1 and ROCK2. [PDF]

open access: yesPLoS ONE, 2012
ROCK1 and ROCK2 are serine/threonine kinases that function downstream of the small GTP-binding protein RhoA. Rho signalling via ROCK regulates a number of cellular functions including organisation of the actin cytoskeleton, cell adhesion and cell ...

14-3-3 Proteins Interact with a Hybrid Prenyl-Phosphorylation Motif to Inhibit G Proteins [PDF]

open access: yes, 2013
Signaling through G proteins normally involves conformational switching between GTP- and GDP-bound states. Several Rho GTPases are also regulated by RhoGDI binding and sequestering in the cytosol.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]

open access: yes, 2002
Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

RhoA, a Possible Target for Treatment of Airway Hyperresponsiveness in Bronchial Asthma

open access: yesJournal of Pharmacological Sciences, 2010
.: Airway hyperresponsiveness to nonspecific stimuli is one of the characteristic features of allergic bronchial asthma. An elevated contractility of bronchial smooth muscle has been considered as one of the causes of the airway hyperresponsiveness.

S-1-propenylcysteine improves TNF-α-induced vascular endothelial barrier dysfunction by suppressing the GEF-H1/RhoA/Rac pathway

open access: yesCell Communication and Signaling, 2021
Background Vascular endothelial barrier function is maintained by cell-to-cell junctional proteins and contributes to vascular homeostasis. Various risk factors such as inflammation disrupt barrier function through down-regulation of these proteins and ...

RhoA activation by hypoxia in pulmonary arterial smooth muscle cells is age and site specific [PDF]

open access: yes, 2004
Hypoxia induces vasoconstriction of pulmonary arteries through contraction of smooth muscle cells (SMCs). The GTPase RhoA regulates smooth muscle contractility and actin cytoskeletal remodeling through the Rho-associated kinase ( ROCK).

Structure of a highly conserved domain of Rock1 required for Shroom-mediated regulation of cell morphology. [PDF]

open access: yesPLoS ONE, 2013
Rho-associated coiled coil containing protein kinase (Rho-kinase or Rock) is a well-defined determinant of actin organization and dynamics in most animal cells characterized to date.

Generation of specific antibodies against the rap1A, rap1B and rap2 small GTP-binding proteins. Analysis of rap and ras proteins in membranes from mammalian cells [PDF]

open access: yes, 1992
Specific antibodies against rap1A and rap1B small GTP-binding proteins were generated by immunization of rabbits with peptides derived from the C-terminus of the processed proteins.

K-Ras mediated murine epidermal tumorigenesis Is dependent upon and associated with elevated Rac1 activity [PDF]

open access: yes, 2011
A common goal for potential cancer therapies is the identification of differences in protein expression or activity that would allow for the selective targeting of tumor vs. normal cells. The Ras proto-oncogene family (K-Ras, H-Ras and N-Ras) are amongst
