While CaMKII has been implicated in learning and memory, the biological role of the other multifunctional CaM kinases, CaMKI and CaMKIV, is largely unknown.

Ca2+/calmodulin-dependent protein kinase kinase-alpha regulates skeletal muscle glucose uptake independent of AMP-activated protein kinase and Akt activation.

Studies in nonmuscle cells have demonstrated that Ca(2+)/calmodulin-dependent protein kinase kinases (CaMKKs) are upstream regulators of AMP-activated protein kinase (AMPK) and Akt.

In skeletal muscle, activation of AMPK and Akt has been implicated in the regulation of glucose uptake.

The objective of this study was to determine whether CaMKKalpha regulates skeletal muscle glucose uptake, and whether it is dependent on AMPK and/or Akt activation.

After 2 weeks, caCaMKKalpha was robustly expressed and increased CaMKI (Thr(177/180)) phosphorylation, a known CaMKK substrate.

|
Akt (Thr(308)) phosphorylation was not altered by CaMKKalpha, and caCaMKKalpha plus insulin stimulation did not increase the insulin-induced phosphorylation of Akt (Thr(308)).

Collectively, these results implicate CaMKKalpha in the regulation of skeletal muscle glucose uptake independent of AMPK and Akt activation.
