STK11 Peptide

STK11, a CAMK Ser/Thr protein kinase, has an essential role in G1 cell cycle arrest. STK11 phosphorylates and activates members of the AMPK-related subfamily of protein kinases. Defects in STK11 are a cause of predisposition to benign and maligant tumors including gastrointestinal and testicular cancers (Peutz-Jeghers syndrome).
