Limited proteolysis of gap junction protein is intrinsic in mammlian lens fiber-cell plasma membranes

Biochemical and Biophysical Research Communications, 1987
We demonstrate that the limited proteolysis of the lens fiber-cell gap junction protein, MP26, is intrinsic in mammalian lens fiber plasma membranes. Incubations of isolated intact bovine lens fiber plasma membranes in buffer alone did not elicit proteolysis of MP26. Incubations in the buffer with detergent, however, resulted in the limited proteolysis

Localization in the synaptic junction of the cyclic amp stimulated intrinsic protein kinase activity of synaptosomal plasma membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1976
Synaptosomal plasma membrane fragments contain a tightly bound protein kinase which can catalyse the phosphorylation of endogenous protein the reaction bein stimulated by cyclic AMP. A fraction enriched in synaptic junctions, which can be isolated from Triton X-100-treated synaptosomal plasma membranes, is also enriched in the cyclic AMP stimulated ...

GTP, as well as ATP, can act as a substrate for the intrinsic protein kinase activity of synaptic plasma membranes

Molecular and Cellular Biochemistry, 1981
GTP as well as ATP can act as phosphate donor for the intrinsic protein kinase activity of synaptic plasma membranes. There are many similarities between the activities observed with ATP or GTP. Both need a divalent cation, Mg2+ being preferred, both are slightly inhibited by Na+, and more strongly by K+, both are inhibited by theophylline and ...

Water relations and an expression analysis of plasma membrane intrinsic proteins in sensitive and tolerant rice during chilling and recovery [PDF]

Cell Research, 2006
A symptom of chilling injury is development of water deficit in shoots, resulting from an imbalance of water transport and transpiration. In this work, two rice varieties (Oryza sativa L. var. Wasetoitsu and Somewake) seedlings were chilled at 7 degrees C, followed by recovery at 28 degrees C. Based on the growth phenotype and electrolyte leakage tests,

The molecular mechanisms of plant plasma membrane intrinsic proteins trafficking and stress response.

Yi chuan = Hereditas, 2017
Plasma membrane intrinsic proteins (PIPs) are plant channel proteins located on the plasma membrane. PIPs transfer water, CO2 and small uncharged solutes through the plasma membrane. PIPs have high selectivity to substrates, suggestive of a central role in maintaining cellular water balance.

Cloning and Sequence Analysis of Gene Encoding Plasma Membranes Intrinsic Protein of Stipa Grandis

2012
Plasma membranes intrinsic proteins (PIPs), a member of aquaporins, mediate water transport in many plant species. In this study, the PCR primers were constructed to correspond to the second and fifth transmembrane domains of PIPs in Hordeum vulgare. Using RT-PCR, 5′ RACE and 3′ RACE, a full-length cDNA of PIP-Type aquaporin Gene was isolated from cDNA

Two rice plasma membrane intrinsic proteins, OsPIP2;4 and OsPIP2;7, are involved in transport and providing tolerance to boron toxicity

Planta, 2013
Boron (B) toxicity is responsible for low cereal crop production in a number of regions worldwide. In this report, we characterized two rice genes, OsPIP2;4 and OsPIP2;7, for their involvement in B permeability and tolerance. Transcript analysis demonstrated that the expression of OsPIP2;4 and OsPIP2;7 were downregulated in shoots and strongly ...

Is expression of aquaporins (plasma membrane intrinsic protein 2s, PIP2s) associated with thermonasty (leaf-curling) in Rhododendron?

Journal of Plant Physiology, 2013
It is postulated that leaf thermonasty (leaf curling) in rhododendrons under sub-freezing temperatures is caused by water redistribution due to extracellular freezing. We hypothesize that aquaporins (AQPs), the transmembrane water-channels, may be involved in regulating water redistribution and thus leaf curling.

Molecular insights into the plasma membrane intrinsic proteins roles for abiotic stress and metalloids tolerance and transport in plants

Indian Journal of Plant Physiology, 2018
Aquaporins are channel proteins reported to play multiple functions in plants ranging from water, solutes, metalloids (arsenic, boron, silicon) transport, and tolerance to abiotic stresses including drought, salinity and cold. Based on their localization and sequence similarities, aquaporins have been classified into seven major subfamilies: plasma ...

Plasma membrane intrinsic protein OsPIP2;6 is involved in root-to-shoot arsenic translocation in rice (Oryza sativa L.)

Plant Cell Reports
This study demonstrates the crucial role of OsPIP2;6 for translocation of arsenic from roots to shoots, which can decrease arsenic accumulation in rice for improved food safety. Arsenic (As) contamination in food and water, primarily through rice consumption, poses a significant health risk due to its natural tendency to accumulate inorganic arsenic ...
