Non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase is post-translationally phosphorylated in heterotrophic cells of wheat (Triticum aestivum)
(Elsevier Science, 2002-10)
In wheat, non-phosphorylating, NADP-dependent glyceraldehyde-3-phosphate dehydrogenase (GAPN) was found to be encoded by one gene giving rise to a single protein. However, Western blots revealed two different subunits of ...
Phosphorylation regulates functions of ZEB1 transcription factor
(Wiley-liss, Div John Wiley & Sons Inc, 2016-03)
ZEB1 transcription factor is important in both development and disease, including many TGFβ-induced responses, and the epithelial-to-mesenchymal transition (EMT) by which many tumors undergo metastasis. ZEB1 is differentially ...
Phosphorylation of arabidopsis MAP kinase phosphatase 1 (MKP1) is required for PAMP responses and resistance against bacteria
(American Society of Plant Biologist, 2017-12)
Plants perceive potential pathogens via the recognition of pathogen-associated molecular patterns (PAMPs) by surface-localized pattern recognition receptors, which initiates a series of intracellular responses that ultimately ...
An ACTH-activated protein tyrosine phosphatase (PTP) is modulated by PKA-mediated phosphorylation
(Taylor, 2000-11)
In adrenal cortex, ACTH regulation of steroidogenesis depends on PKA-dependent serine/threonine phosphorylation and also on the activity of protein tyrosine phosphatases (PTPs). In addition, ACTH increases total PTPs ...
Phosphorylation of the TGBp1 movement protein of Potato virus X by a Nicotiana tabacum CK2-like activity
(Elsevier Science, 2008-10)
The movement protein (MP) TGBp1 of the potexvirus Potato virus X (PVX) is a multifunctional protein required for cell-to-cell movement within the host plant. Recent work on other plant viruses has indicated that MP ...
Assembly of the Complexes of the Oxidative Phosphorylation System in Land Plant Mitochondria
(Annual Reviews, 2019-04)
Plant mitochondria play a major role during respiration by producing the ATP required for metabolism and growth. ATP is produced during oxidative phosphorylation (OXPHOS), a metabolic pathway coupling electron transfer ...
Differential phosphorylation of the N‐terminal extension regulates phytochrome B signaling
(Wiley Blackwell Publishing, Inc, 2019-11)
Phytochrome B (phyB) is an excellent light quality and quantity sensor that can detect subtle changes in the light environment. The relative amounts of the biologically active photoreceptor (phyB Pfr) are determined by the ...
Acidic ribosomal P proteins are phosphorylated in Trypanosoma cruzi
(Elsevier, 2001-12)
Trypanosoma cruzi ribosomes from epimastigote forms were purified as determined by electron microscopy and isoelectrofocusing was used to analyse this purified ribosome fraction. Silver stained gels revealed that acidic ...
Evidence for the involvement of Proline-rich Tyrosine Kinase 2 (PYK2) in tyrosine phosphorylation downstream of PKA activation during human sperm capacitation
(Oxford University Press, 2014-09-01)
Sperm capacitation involves an increase in intracellular Ca(2+) concentration as well as in protein kinase A (PKA)-dependent protein tyrosine (Tyr) phosphorylation. Interestingly, in humans, a decrease in extracellular ...
Human sperm subpopulations: relationship between functional quality and protein tyrosine phosphorylation
(European Society of Human Reproduction and Embriology, 2004-12)
Human semen is composed of a heterogeneous population of sperm with varying degrees of structural and functional differentiation and normality, which result in subpopulations of different quality.
Using a discontinuous ...
