Regulators of G protein signalling proteins in the human myometrium [PDF]

open access: yes, 2009
The contractile state of the human myometrium is controlled by extracellular signals that promote relaxation or contraction. Many of these signals function through G proteincoupled receptors at the cell surface, stimulating heterotrimeric G proteins and ...

Regulation of phospholipase C-delta by GTP-binding proteins-rhoA as an inhibitory modulator

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1998
The regulation of Phospholipase C (PLC)delta activity remains obscure. These studies show that PLCdelta1 activity is significantly enhanced by both guanosine thiotriphosphate (GTPgammaS) and Clostridium botulinum exoenzyme C3 (C3) but not by aluminium fluoride.

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension

open access: yesAdvanced Science, EarlyView.
H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...

Both Ligand- and Cell-Specific Parameters Control Ligand Agonism in a Kinetic Model of G Protein–Coupled Receptor Signaling [PDF]

open access: yes, 2007
G protein–coupled receptors (GPCRs) exist in multiple dynamic states (e.g., ligand-bound, inactive, G protein–coupled) that influence G protein activation and ultimately response generation. In quantitative models of GPCR signaling that incorporate these

Small GTP-binding protein PdRanBP regulates vascular tissue development in poplar

open access: yesBMC Genetics, 2016
Previous research has demonstrated that ectopic expression of Ran-binding protein (RanBP) in Arabidopsis results in more axillary buds and reduced apical dominance compared to WT plants. However, the function of RanBP in poplar, which has very typical secondary growth, remains unclear.

Allele‐Specific Regulation of PAXIP1‐AS1 by SMC3/CEBPB at rs112651172 in Psychiatric Disorders Drives Synaptic and Behavioral Dysfunctions in Mice

open access: yesAdvanced Science, EarlyView.
This study identifies a functional noncoding variant, rs112651172 (C/G), that drives allele‐specific expression of PAXIP1‐AS1 in monozygotic twin pairs discordant for schizophrenia and bipolar disorder. The risk G allele enhances CEBPB binding, leading to lncRNA upregulation, CNTNAP3 derepression, and synaptic and behavioral deficits in mice.

Open and cut: allosteric motion and membrane fission by dynamin superfamily proteins. [PDF]

open access: yes, 2019
Cells have evolved diverse protein-based machinery to reshape, cut, or fuse their membrane-delimited compartments. Dynamin superfamily proteins are principal components of this machinery and use their ability to hydrolyze GTP and to polymerize into ...

The architecture of the Rag GTPase signaling network [PDF]

open access: yes, 2017
The evolutionarily conserved target of rapamycin complex 1 (TORC1) couples an array of intra- and extracellular stimuli to cell growth, proliferation and metabolism, and its deregulation is associated with various human pathologies such as ...

Estrogen Alleviates Sevoflurane‐Induced Neurotoxicity by Inhibiting ERα‐Tau Binding

open access: yesAdvanced Science, EarlyView.
Sevoflurane‐induced neurotoxicity exhibits sex differences, and estrogen can mitigate these effects; however, its protective action appears to be time‐window dependent, which may be related to the competitive binding of estrogen and Tau to ERα. Abstract Sevoflurane‐induced neurotoxicity is age‐dependent, but the role of sex differences is unclear ...

Dynamic cofilin phosphorylation in the control of lamellipodial actin homeostasis [PDF]

open access: yes, 2007
During animal cell chemotaxis, signalling at the plasma membrane induces actin polymerisation to drive forward cell movement. Since the cellular pool of actin is limited, efficient protrusion formation also requires the coordinated disassembly of pre ...
