== Function ==
[https://www.uniprot.org/uniprot/CSK2A_MAIZE CSK2A_MAIZE] Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. The alpha chain contains the catalytic site.

== Publication Abstract from PubMed ==
The structures of the catalytic subunit of protein kinase CK2 from Zea mays complexed with Mg2+ and with analogs of ATP or GTP were determined to 2.2 A resolution. Unlike most other protein kinases, CK2 from various sources shows 'dual-cosubstrate specificity', that is, the ability to efficiently use either ATP or GTP as a cosubstrate. The structures of these complexes demonstrate that water molecules are critical to switch the active site of CK2 from an ATP- to a GTP-compatible state. An understanding of the structural basis of dual-cosubstrate specificity may help in the design of drugs that target CK2 or other kinases with this property.

GTP plus water mimic ATP in the active site of protein kinase CK2.,Niefind K, Putter M, Guerra B, Issinger OG, Schomburg D Nat Struct Biol. 1999 Dec;6(12):1100-3. PMID:10581548<ref>PMID:10581548</ref>
