Molecular Cloning and Expression of Three Isoforms of the 100-kDa a Subunit of the Mouse Vacuolar Proton-translocating ATPase [PDF]

Journal of Biological Chemistry, 2000
We have identified cDNAs encoding three isoforms (a1, a2, and a3) of the 100-kDa a subunit of the mouse vacuolar proton-translocating ATPase (V-ATPase). The predicted protein sequences of the three isoforms are 838, 856, and 834 amino acids, respectively, and they display approximately 50% identity between isoforms.

Vacuolar Acidification and Bafilomycin-Sensitive Proton Translocating ATPase in Human Epidermal Langerhans Cells

Journal of Investigative Dermatology, 1991
Langerhans cells (LC) are the principal antigen-presenting cells (APC) of squamous epithelia. We have previously shown that freshly isolated LC (fLC) are able to deliver endocytosed membrane MHC class II molecules into acidic environments, and that this capacity is lost when LC are placed in culture (cLC).

Identification of inhibitors of vacuolar proton-translocating ATPase pumps in yeast by high-throughput screening flow cytometry [PDF]

Analytical Biochemistry, 2010
Fluorescence intensity of the pH-sensitive carboxyfluorescein derivative 2,7-bis(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF) was monitored by high-throughput flow cytometry in living yeast cells. We measured fluorescence intensity of BCECF trapped in yeast vacuoles, acidic compartments equivalent to lysosomes where vacuolar proton-translocating ...

Identification of a Domain in the Vo Subunit d That Is Critical for Coupling of the Yeast Vacuolar Proton-translocating ATPase [PDF]

Journal of Biological Chemistry, 2006
Vacuolar proton-translocating ATPase pumps consist of two domains, V(1) and V(o). Subunit d is a component of V(o) located in a central stalk that rotates during catalysis. By generating mutations, we showed that subunit d couples ATP hydrolysis and proton transport.

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Plant responses to iron nutrition with emphasis on the underutilized crop tef (Eragrostis tef): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Genomic variation drives plant flavor diversification

Journal of Integrative Plant Biology, EarlyView.
This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Interaction of dibutyltin-3-hydroxyflavone bromide with the 16 kDa proteolipid indicates the disposition of proton translocation sites of the vacuolar ATPase [PDF]

Biochemical Journal, 1996
The organotin complex dibutyltin-3-hydroxyflavone bromide [Bu2Sn(of)Br] has been shown to bind to the 16 kDa proteolipid of Nephrops norvegicus, either in the form of the native protein or after heterologous expression in Saccharomyces and assembly into a hybrid vacuolar H+-ATPase.
