Here, we demonstrate that 8-nitro-cGMP potentially S-guanylates thiol groups of cGMP-dependent protein kinase (PKG), the enzyme that serves as one of the major receptor proteins for intracellular cGMP and controls a variety of cellular responses.

Protein expressions of phosphorylated AMP-activated protein kinase-α (AMPKα), phosphorylated endothelial nitric oxide synthase (eNOS), and manganese-dependent superoxide dismutase (Mn-SOD) were decreased, whereas protein expressions of collagen I, transforming growth factor-β1, and Runx2 were increased in aortas of KL(+/-) mice fed on HFD.

Individual loss of either atypical protein kinase C (aPKC) isoform, PKCζ or PKCλ/ι, partially impairs asymmetric divisions and increases CD8(+) T lymphocyte differentiation toward a long-lived effector fate at the expense of memory T cell formation.

Through in vitro and in vivo analysis of HAE phosphorylation, we provide evidence that a conserved phosphorylation site on a region of the HAE protein kinase domain known as the activation segment positively regulates HAE activity.

The pseudokinase, Mixed Lineage Kinase Domain-Like (MLKL), is the most terminal known obligatory effector in the necroptosis pathway, and is activated following phosphorylation by Receptor Interacting Protein Kinase-3 (RIPK3).

Together, Protein Kinase A, Casein Kinase 1 and Glycogen Synthase Kinase 3 silence the pathway in the absence of ligand by phosphorylating Ci at a defined cluster of sites, thereby promoting its proteolytic conversion to a transcriptional repressor (Ci-75).
