What is a CK2 inhibitor?

Abstract. Casein kinase II (CK2) is an ubiquitous and pleiotropic serine/threonine protein kinase able to phosphorylate hundreds of substrates. Being implicated in several human diseases, from neurodegeneration to cancer, the biological roles of CK2 have been intensively studied.

How does protein kinase inhibitor work?

They act by adding a phosphate group to a protein (phosphorylation), usually on a specific amino acid which often makes the protein or enzyme “active”.

What is dual specificity protein kinase?

In biochemistry, a dual-specificity kinase (EC 2.7. 12.1) is a kinase that can act as both tyrosine kinase and serine/threonine kinase.

What is CK2 enzyme?

CK2 is a protein kinase responsible for phosphorylation of substrates in various pathways within a cell; ATP or GTP can be used as phosphate source. CK2 has a dual functionality with involvement in cell growth/proliferation and suppression of apoptosis.

Does protein kinase A use GTP as a substrate?

GTP, as well as ATP, can act as a substrate for the intrinsic protein kinase activity of synaptic plasma membranes. Mol Cell Biochem.

What are the role of protein kinases?

Protein kinases (PTKs) are enzymes that regulate the biological activity of proteins by phosphorylation of specific amino acids with ATP as the source of phosphate, thereby inducing a conformational change from an inactive to an active form of the protein.

What is the CK2 gene?

CK2 is a constitutively active Ser/Thr protein kinase, which phosphorylates hundreds of substrates, controls several signaling pathways, and is implicated in a plethora of human diseases. Its best documented role is in cancer, where it regulates practically all malignant hallmarks.

How do protein kinases recognize their substrates?

Kinases target their substrates through a combination of catalytic domain interactions both proximal and distal to the active site, interactions of short linear sequence motifs with protein interaction modules, and indirect interactions mediated by adaptor or scaffold proteins.
