Calcium/Calmodulin-dependent Protein Kinase Kinase 2 (CaMKK2) is a member of the CaMK family that contains a central Ser/Thr kinase domain followed by a regulatory domain consisting of overlapping autoinhibitory and CaM-binding regions. CaMKK2 can be distinguished from other CaMK family members by the presence of a unique Pro/Arg/Gly-rich insert following the ATP-binding domain. CaMKK2 phosphorylates CaMKI at Thr177 and CaMKIV at Thr200. CaMKK2 also phosphorylates AMPKalpha in response to calcium. CaMKK2 has been implicated in long-term memory formation and adipocyte development. CaMKK2 is phosphorylated at Ser511 by death-associated protein kinase (DAPK) in a signaling cascade thought to be involved in neuronal death.
