|Product Overview:||CK2 Kinase (Human) Assay/Inhibitor Screening Assay Kit is a single-site, non-quantitative immunoassay for CK2 activity. Plates are pre-coated with a substrate corresponding to recombinant p53, which contains a serine residue that are phosphorylated by CK2 (Casein kinase II). The detector antibody specifically detects only the phosphorylated form of serine46 on p53.|
|Description:||Protein kinase Casein kinase II (CK2) is a ubiquitous and pleiotropic seryl/threonyl protein kinase, which appears to interact with different signaling pathways and therefore represents the prototype of a multifunctional protein kinase. The holoenzymeis generally composed of two catalytic (alpha and/or alpha") and two regulatory (beta) subunits, but the free alpha/alpha" subunit are catalytically active by themselves. Although the beta subunits deeply affect many properties of CK2, both the isolated catalytic subunit and holoenzyme are constitutively active. The enzyme is highly expressed in most cancers and this higher expression has been tentatively correlated with the involvement of CK2 in the promotion of specific phases of the cell cycle. Unlike the majority of protein kinases, which are tightly regulated enzymes, CK2 is endowed with high constitutive activity, a feature that is suspected to underlie its oncogenic potential and possible implication in viral infection. This makes CK2 an attractive target for anti-neoplastic and antiviral drugs.|
