CAMKK1 a calcium/calmodulin-dependent S/T protein kinase of the CAMKK family. Phosphorylates CAMK1, CAMK1D, CAMK1G and CAMK4. Involved in regulating cell apoptosis. Promotes cell survival by phosphorylating AKT1/PKB that inhibits pro-apoptotic BAD/Bcl2-antagonist of cell death. 2 isoforms of the human protein are produced by alternative splicing. The autoinhibitory domain overlaps with the calmodulin binding region and may be involved in intrasteric autoinhibition. Binding of calmodulin may releave intrasteric autoinhibition. May be regulated through phosphorylation by CAMK1 and CAMK4. Appears to be autophosphorylated in a Ca2+/calmodulin-dependent manner. Phosphorylation of Ser-458 is blocked upon binding to Ca2+/calmodulin. Note: This description may include information from UniProtKB.
