Casein kinase II alpha 1 subunit
Casein kinase II alpha subunit
Casein kinase II subunit alpha
CK II alpha
CK2 catalytic subunit alpha
功能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.
序列相似性Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CK2 subfamily. Contains 1 protein kinase domain.
