[Back to Kinase CDK2]
Substrate: CSNK2A1

Description: Casein kinase II subunit alpha (EC 2.7.11.1) (CK II).

Synonyms: CK2A1

Ensembl ID: ENSG00000101266

UniprotKB/SwissProt: CSK21_HUMAN (P68400)

Function: Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. The alpha and alpha' chains contain the catalytic site. Participates in Wnt signaling. CK2 phosphorylates 'Ser-392' of p53/TP53 following UV irradiation.
