Controversial Regulation of Gene Expression and Protein Transduction of Aquaporins under Drought and Salinity Stress

Plants, 2020
Enhancement of the passage of water through membranes is one of the main mechanisms via which cells can maintain their homeostasis under stress conditions, and aquaporins are the main participants in this process. However, in the last few years, a number

The impact of the absence of aliphatic glucosinolates on water transport under salt stress in Arabidopsis thaliana

Frontiers in Plant Science, 2015
Members of the Brassicaceae are known for their contents of nutrients and health-promoting phytochemicals, including glucosinolatesExposure to salinity increases the levels of several of these compounds, but their role in abiotic stress response is ...

MG53 Preserves Neuromuscular Junction Integrity and Alleviates ALS Disease Progression

Antioxidants, 2021
Respiratory failure from progressive respiratory muscle weakness is the most common cause of death in amyotrophic lateral sclerosis (ALS). Defects in neuromuscular junctions (NMJs) and progressive NMJ loss occur at early stages, thus stabilizing and ...

Water channel activities of Mimosa pudica plasma membrane intrinsic proteins are regulated by direct interaction and phosphorylation [PDF]

FEBS Letters, 2005
cDNAs encoding aquaporins PIP1;1, PIP2;1, and TIP1;1 were isolated from Mimosa pudica (Mp) cDNA library. MpPIP1;1 exhibited no water channel activity; however, it facilitated the water channel activity of MpPIP2;1 in a phosphorylation‐dependent manner. Mutagenesis analysis revealed that Ser‐131 of MpPIP1;1 was phosphorylated by PKA and that cooperative

Ectopic expression of Arabidopsis thaliana plasma membrane intrinsic protein 2 aquaporins in lily pollen increases the plasma membrane water permeability of grain but not of tube protoplasts [PDF]

New Phytologist, 2008
To investigate the role of aquaporin-mediated water transport during pollen grain germination and tube growth, Arabidopsis thaliana plasma membrane intrinsic proteins (PIPs) were expressed in pollen of Lilium longiflorum (lily). Successful expression of AtPIPs in particle-bombarded lily pollen grains was monitored by co-expression with fluorescent ...

Identification of Putative Aquaporin Genes and Their Expression Analysis under Hypoxic Conditions in Soybean [Glycine max (L.) Merr.]

Plant Production Science, 2012
The aims of this study were to detect plasma-membrane intrinsic protein type 2 (PIP2) genes of soybean (cv. Enrei) and to analyze mRNA levels of these genes under normoxic (control) and hypoxic conditions. A sequence similarity search with cDNA sequences

Surface expression and subunit specific control of steady protein levels by the Kv7.2 helix A-B linker.

PLoS ONE, 2012
Kv7.2 and Kv7.3 are the main components of the neuronal voltage-dependent M-current, which is a subthreshold potassium conductance that exerts an important control on neuronal excitability.

Functional interactome of Aquaporin 1 sub-family reveals new physiological functions in Arabidopsis Thaliana [PDF]

Network Biology, 2013
Aquaporins are channel proteins found in plasma membranes and intercellular membranes of different cellular compartments, facilitate the water flux, solutes and gases across the cellular plasma membranes.

Relative abundance of integral plasma membrane proteins in Arabidopsis leaf and root tissue determined by metabolic labeling and mass spectrometry.

PLoS ONE, 2013
Metabolic labeling of proteins with a stable isotope ((15)N) in intact Arabidopsis plants was used for accurate determination by mass spectrometry of differences in protein abundance between plasma membranes isolated from leaves and roots.
