Acidic pH triggers the phosphorylation of the response regulator NtrX in alphaproteobacteria
(Public Library of Science, 2018-04)
Many signaling pathways that control cellular development, cell-cycle progression and nutritional versatility have been studied in Caulobacter crescentus. For example, it was suggested that the response regulator NtrX is ...
The Rv1712 locus from Mycobacterium tuberculosis H37Rv codes for a functional CMP kinase that preferentially Phosphorylates dCMP
(2009-04-01)
The Mycobacterium tuberculosis cmk gene, predicted to encode a CMP kinase (CMK), was cloned and expressed, and its product was purified to homogeneity. Steady-state kinetics confirmed that M. tuberculosis CMK is a monomer ...

DNA mismatch repair activity of MutLα is regulated by CK2-dependent phosphorylation of MLH1 (S477)
(Wiley-liss, Div John Wiley & Sons Inc, 2018-12)
MutLα, a heterodimer consisting of MLH1 and PMS2, is a key player of DNA mismatch repair (MMR), yet little is known about its regulation. In this study, we used mass spectrometry to identify phosphorylated residues within ...
The Activity of the Chloroplastic Ndh Complex Is Regulated by Phosphorylation of the NDH-F Subunit
(American Society of Plant Biologists, 2003-05-01)
Hydrogen peroxide (H2O2) induces increases, to different degrees, in transcripts, protein levels, and activity of the Ndh complex (EC 1.6.5.3). In the present work, we have compared the effects of relatively excess light, ...
Crosstalk between insulin and angiotensin II signalling systems
(Johann Ambrosius Barth VerlagHeidelbergAlemanha, 1999)
Subcellular distribution of ERK phosphorylation in tyrosine and threonine depends on redox status in murine lung cells
(Public Library of Science, 2018-02)
Activation of ERK1/2 implies the phosphorylation of tyrosine (pTyr) and threonine (pThr) by MEK1/2; both reactions were thought to be cytoplasmic, promoting ERK to reach the nucleus where it activates several transcription ...
Analysis of rotavirus non-structural protein NSP5 by mass spectrometry reveals a complex phosphorylation pattern
(ELSEVIER, 2010)
Genomic replication and partial assembly of Rotavirus takes place in cytoplasmic viral structures called
viroplasms. NSP5 is a viral phosphoprotein localized in viroplasms and its expression is imperative for
viral cycle ...
Phosphorylation or Mutation of the ERK2 Activation Loop Alters Oligonucleotide Binding
(American Chemical Society, 2016-03)
The mitogen-activated protein kinase ERK2 is able to elicit a wide range of context-specific responses to distinct stimuli, but the mechanisms underlying this versatility remain in question. Some cellular functions of ERK2 ...
