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 ...

The release of Agrin by motoneurons activates the muscle-specific receptor tyrosine kinase (MuSK) as the main organizer of subsynaptic specializations at the neuromuscular junction. MuSK downstream signaling is largely ...

The effect of CK2 beta on the activity of CK2 alpha and other protein kinases that can bind this regulatory subunit is not fully understood. In an attempt to improve our understanding of this effect, chimeras of CK2 alpha ...

Multiple phosphorylation of beta-catenin by glycogen synthase kinase 3 (GSK3) in the Wnt pathway is primed by CK1 through phosphorylation of Ser-45, which lacks a typical CK1 canonical sequence. Synthetic pepticles ...

Protein kinase CK2 (also known as casein kinase 2) is present in the cytoplasm, nuclei, and several other organelles. In addition, this enzyme has been found bound to the external side of the cell membrane where it acts ...

Protein kinase CK2 (also known as casein kinase 2) has catalytic (α, α′) and regulatory (β) subunits. The role of carboxyl amino acids in positions from 324 to 328 was studied for Xenopus laevis CK2α. Deletions and mutations ...

Rotavirus NSP5 is a nonstructural protein that localizes in viro-plasms of virus-infected cells. NSP5 interacts with NSP2 and undergoes a complex post-translational hyperphosphorylation, generating species with reduced ...
