    text
  • cytoplasmic localization of CAMKK1 depends on CRM1-mediated nuclear export mediated through a Rev-like nuclear export signal in the CAMKK1 regulatory domain
  • basic FUNCTION
  • playing a role in the calcium/calmodulin-dependent (CaM) kinase cascade
  • phosphorylating CAMK1, CAMK1D, CAMK1G and CAMK4
  • involved in regulating cell apoptosis
  • promoting cell survival by phosphorylating AKT1/PKB that inhibits pro-apoptotic BAD/Bcl2-antagonist of cell death
  • stimulates glucose uptake via insulin-independent signaling mechanisms
  • implicated in the regulation of skeletal muscle glucose uptake independent of PRKAB1 and AKT1 activation
  • important new role for CAMKK1 in the differentiation of monocytic cells
  • capable of activating BRSK1 through phosphorylation of Thr (189)and CaMKK1 may be an alternative activating kinase for BRSK1
  • CAMKK1-induced phosphorylation of DNM1L regulates mitochondrial morphology (
  • 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
