LKB1 Is the Upstream Kinase in the AMP-Activated Protein Kinase Cascade
Open accessAbstract
Inactivating mutations in the protein kinase LKB1 lead to a dominantly inherited cancer in humans termed Peutz-Jeghers syndrome. The role of LKB1 is unclear, and only one target for LKB1 has been identified in vivo [3]. AMP-activated protein kinase (AMPK) is the downstream component of a protein kinase cascade that plays a pivotal role in energy homeostasis. AMPK may have a role in protecting the body from metabolic diseases including type 2 diabetes, obesity, and cardiac hypertrophy. We previously reported the identification of three protein kinases (Elm1, Pak1, and Tos3 [9]) that lie upstream of Snf1, the yeast homologue of AMPK. LKB1 shares sequence similarity with Elm1, Pak1, and Tos3, and we demonstrated that LKB1 phosphorylates AMPK on the activation loop threonine (Thr172) within the catalytic subunit and activates AMPK in vitro [9]. Here, we have investigated whether LKB1 corresponds to the major AMPKK activity present in cell extracts. AMPKK purified from rat liver corresponds to LKB1, and blocking LKB1 activity in cells abolishes AMPK activation in response to different stimuli. These results identify a link between two protein kinases, previously thought to lie in unrelated, distinct pathways, that are associated with human diseases.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
