Quantitative in vivo phosphoproteomics reveals reversible signaling processes during nitrogen starvation and recovery in the biofuel model organism Chlamydomonas reinhardtii

open access: yesBiotechnology for Biofuels, 2017
Background Nitrogen deprivation and replenishment induces massive changes at the physiological and molecular level in the green alga Chlamydomonas reinhardtii, including reversible starch and lipid accumulation.

Mechanism of metabolic control. Target of rapamycin signaling links nitrogen quality to the activity of the Rtg1 and Rtg3 transcription factors. [PDF]

open access: yes, 2000
De novo biosynthesis of amino acids uses intermediates provided by the TCA cycle that must be replenished by anaplerotic reactions to maintain the respiratory competency of the cell. Genome-wide expression analyses in Saccharomyces cerevisiae reveal that

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Phosphoprotein Phosphatase Activity in the Thyroid

open access: yesExperimental Biology and Medicine, 1975
Phosphoprotein phosphatase activity in the calf thyroid was found in various subcellular fractions. The relative amount in each fraction varied according to the substrate used: The 500g fraction had the highest specific activity when protamine was used, while the 5000g fraction was highest when histone was used. Triton X-100 tended to increase activity

Quantitative and functional post-translational modification proteomics reveals that TREPH1 plays a role in plant thigmomorphogenesis

open access: yes, 2018
Plants can sense both intracellular and extracellular mechanical forces and can respond through morphological changes. The signaling components responsible for mechanotransduction of the touch response are largely unknown.

Mass Spectrometry-based Methods for Phosphorylation Site Mapping of Hyperphosphorylated Proteins Applied to Net1, a Regulator of Exit from Mitosis in Yeast [PDF]

open access: yes, 2002
Prior to anaphase in Saccharomyces cerevisiae, Cdc14 protein phosphatase is sequestered within the nucleolus and inhibited by Net1, a component of the RENT complex in budding yeast. During anaphase the RENT complex disassembles, allowing Cdc14 to migrate

Reduced Dietary Protein Induces Changes in the Dental Proteome

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Low dietary protein (10%) from normal (20%) does change protein expression in tooth proteome and alter developmental pathways. Among the significant protein expressions changes are actin‐based myosins, tooth, and bone development proteins. Perplexingly tooth size is not altered, suggesting more nuanced phenotypic response to low dietary protein in ...

Systematic Global Analysis of Genes Encoding Protein Phosphatases in Aspergillus fumigatus. [PDF]

open access: yes, 2015
Aspergillus fumigatus is a fungal pathogen that causes several invasive and noninvasive diseases named aspergillosis. This disease is generally regarded as multifactorial, considering that several pathogenicity determinants are present during the ...

Human Cyclophilins—An Emerging Class of Drug Targets

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Cyclophilins are a family of enzymes with peptidyl‐prolyl isomerase activity found in all cells of all organisms. To date, 17 cyclophilin isoforms have been identified in the human body, participating in diverse biological processes. Consequently, cyclophilins have emerged as promising targets for drug development to address a wide array of ...

Transient calcium and dopamine increase PKA activity and DARPP-32 phosphorylation.

open access: yesPLoS Computational Biology, 2006
Reinforcement learning theorizes that strengthening of synaptic connections in medium spiny neurons of the striatum occurs when glutamatergic input (from cortex) and dopaminergic input (from substantia nigra) are received simultaneously.
