CK1 constitutes a protein kinase subfamily that is involved in many important physiological processes. However, there is limited knowledge about mechanisms that regulate their activity. Isoforms CK1δ and CKlε were previously ...

Protein kinase CK2 (also known as casein kinase II) is a ubiquitous eukaryotic ser/thr protein kinase present in the nucleus and cytoplasm. CK2 is known to phosphorylate more than 100 substrates, many of which are involved ...

In response to light, as part of a two-component system, the Brucella blue light-activated histidine kinase (LOV-HK) increases its autophosphorylation, modulating the virulence of this microorganism. The Brucella histidine ...

PKA (cAMP-dependent protein kinase) activity, as well as that of other AGC members, is regulated by multiple phosphorylations of its catalytic subunits. In Saccharomyces cerevisiae, the PKA regulatory subunit is encoded ...

2-Cys peroxiredoxins are peroxidases devoid of prosthetic groups that mediate in the defence against oxidative stress and the peroxide activation of signaling pathways. This dual capacity relies on the high reactivity of ...

cAMP-dependent protein kinase (PKA) catalytic (C) and regulatory (R) subunits from Yarrowia lipolytica are encoded by single genes, TPK1 and RKA1, respectively. Here we performed the heterologous expression, purification ...

Four members of the potato (Solanum tuberosum L.) calcium-dependent protein kinase (CDPK) family StCDPK22/23/24 and StCDPK27, present three functional EF-hands motifs in their calmodulin-like domain (CLD). StCDPK22/23/24 ...

The yeast Spf1p P5A-ATPase actively translocates membrane spanning peptides of mislocalized proteins from the endoplasmic reticulum. Loss of Spf1p function causes a pleiotropic ER stress-phenotype associated with alterations ...
