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 of GroEL, DnaK and other proteins from Thiobacillus ferrooxidans grown under different conditions
(Blackwell Publishing Ltd, 1996)
The levels of phosphorylation of the chaperones DnaK and GroEL and other proteins varied when cells of Thiobacillus ferrooxidans were subjected to phosphate starvation. The phosphorylated amino acid of GroEL was found to ...
Membrane actions of male contraceptive gossypol tautomers
(1986)
The role of different gossypol tautomers in the interaction of this molecule with membranes has been investigated using the isolated hemiacetal moiety of gossypol and the pH dependency of the keto-enol tautomeric equilibrium. ...
The catalytic subunit of schizosaccharomyces pombe CK2 (Cka1) negatively regulates RNA polymerase II transcription through phosphorylation of positive cofactor 4 (PC4)
(MDPI, 2022)
Positive cofactor 4 (PC4) is a transcriptional coactivator that plays important roles in
transcription and DNA replication. In mammals, PC4 is phosphorylated by CK2, and this event
downregulates its RNA polymerase II ...
The phosphorylation of nucleoplasmin by casein kinase-2 is resistant to heparin inhibition
(1987)
Highly purified preparations of casein kinase-2 from the nuclei of Xenopus laevis oocytes and from calf thymus can phosphorylate in vitro purified nucleoplasmin from X. laevis oocytes and eggs. The phosphorylation of ...
Chemical dissection of the APC repeat 3 multistep phosphorylation by the concerted action of protein kinases CK1 and GSK3
(2007)
A crucial event in machinery controlled by Wnt signaling is the association of β-catenin with the adenomatous polyposis coli (APC) protein, which is essential for the degradation of β-catenin and requires the multiple ...
Role of flanking sequences and phosphorylation in the recognition of the simian-virus-40 large T-antigen nuclear localization sequences by importin-alpha
(Portland Press, 2003-10-15)
The nuclear import of simian-virus-40 large T-antigen (tumour antigen) is enhanced via phosphorylation by the protein kinase CK2 at Ser(112) in the vicinity of the NLS (nuclear localization sequence). To determine the ...

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 ...
