Membrane-mediated protein interactions drive membrane protein organization

Nature Communications, 2022
The plasma membrane’s main constituents, i.e., phospholipids and membrane proteins, are known to be organized in lipid-protein functional domains and supercomplexes. No active membrane-intrinsic process is known to establish membrane organization.

Expression and functional analysis of the rice plasma-membrane intrinsic protein gene family [PDF]

Cell Research, 2006
Plasma membrane intrinsic proteins (PIPs) are a subfamily of aquaporins that enable fast and controlled translocation of water across the membrane. In this study, we systematically identified and cloned ten PIP genes from rice. Based on the similarity of the amino acid sequences they encoded, these rice PIP genes were classified into two groups and ...

Heterologous Expression of Two Jatropha Aquaporins Imparts Drought and Salt Tolerance and Improves Seed Viability in Transgenic Arabidopsis thaliana. [PDF]

PLoS ONE, 2015
Drought and high salinity are environmental conditions that cause adverse effects on the growth and productivity of crops. Aquaporins are small integral membrane proteins that belong to the family of the major intrinsic proteins (MIPs), with members in ...

Barley plasma membrane intrinsic proteins (PIP Aquaporins) as water and CO2 transporters [PDF]

Pflügers Archiv - European Journal of Physiology, 2008
We identified barley aquaporins and demonstrated that one, HvPIP2;1, transports water and CO2. Regarding water homeostasis in plants, regulations of aquaporin expression were observed in many plants under several environmental stresses. Under salt stress, a number of plasma membrane-type aquaporins were down-regulated, which can prevent continuous ...

Extracellular high molecular weight α-synuclein oligomers induce cell death by disrupting the plasma membrane

npj Parkinson's Disease, 2023
α-Synuclein (αS), the causative protein of Parkinson’s disease and other α-synucleinopathies, aggregates from a low molecular weight form (LMW-αS) to a high molecular weight αS oligomer (HMW-αSo).

Comparing Hydraulics Between Two Grapevine Cultivars Reveals Differences in Stomatal Regulation Under Water Stress and Exogenous ABA Applications

Frontiers in Plant Science, 2020
Hydraulics of plants that have different strategies of stomatal regulation under water stress are relatively poorly understood. We explore how root and shoot hydraulics, stomatal conductance (gs), leaf and root aquaporin (AQP) expression, and abscisic ...

Arabidopsis plasma membrane intrinsic protein (AtPIP2;1) is implicated in a salinity conditional influence on seed germination

Functional Plant Biology, 2023
Dynamic changes in aquaporin gene expression occur during seed germination. One example is the ~30-fold increase in Arabidopsis thaliana PIP2;1 transcripts within 24 h of seed imbibition. To investigate whether AtPIP2;1 can influence seed germination wild-type Columbia-0, single (Atpip2;1) and double (Atpip2;1-Atpip2;2) loss-of-function mutants, along ...

Transmembrane Helices 2 and 3 Determine the Localization of Plasma Membrane Intrinsic Proteins in Eukaryotic Cells [PDF]

Frontiers in Plant Science, 2020
In plants, plasma membrane intrinsic protein (PIP) PIP1s and PIP2s mediate the transport of disparate substrates across plasma membranes (PMs), with a prerequisite that the proteins correctly localize to the PMs. While PIP2s can take correct localization by themselves in plant cells, PIP1s cannot unless aided by a specific PIP2.

Aquaporin-mediated stress signaling cascade in plants

Plant Stress, 2023
Environments affected plant growth and development, while their change resulted in various stresses in higher plants. Aquaporins (AQPs) were the major intrinsic proteins (MIPs), which participated in the water channel, and kept the water balance for ...

Aquaporin expression during seed osmopriming and post-priming germination in spinach

Biologia Plantarum, 2013
Aquaporins (AQPs) are proteinaceous channels known to regulate transmembrane water transport, and therefore may be important component of imbibition during osmopriming and germination.
