Protein Kinase CK2

CK2 Product Line

CK2 as Drug Target

CK2 plays a role in a number of cellular processes, including maintenance of cell viablity, protection of cells from apoptosis, cellular stress response. Its overexpression is associated with tumor development and CK2 has been shown to be involved in a variety of other diseases, such as glomerulonephritis, globozoospermia, inflammatory and autoimmune disease, cardiac hypertrophy. Hence, CK2 is considered a promising drug target.

CK2 Product Line

KinaseDetect offers the most complete CK2 product line. We provide all three subunits (alpha 1, alpha 2, beta), deletion mutants, holoenzymes containing either the alpha 1 or alpha 2 subunit as well as monoclonal antibodies against the catalytic and regulatory subunits.
