    basic FUNCTION
  • serine/threonine protein kinase, calcium/calmodulin dependent
  • acting upstream of AMP-activated protein kinase in mammalian cells
  • has potentially a male-specific function in hippocampal memory formation and we have identified male-restricted transcription occurring during hippocampal memory formation
  • regulates hypothalamic production of the orexigenic hormone NPY and contributes to the regulation of energy balance
  • with STK11, catalyzing activation of PRKAB1 by phosphorylation at Thr172
  • act as regulatory enzymes for downstream protein kinases in various Ca2+-dependent cellular processes
  • mediates potentially novel Ca2+-signaling pathway(s), which are independent of downstream protein kinases
  • isoform-specific function for CAMKK2 that regulates ubiquitin signaling at the centrosome and thereby orchestrates dendrite patterning, with important implications for neuronal connectivity in the brain
  • role for CAMKK2 in the restriction of granulocytic fate commitment and differentiation of myeloid progenitor cells
  • CAMKK2 and PRKAB1 function in a signaling pathway that participates in the regulation of adiposity
