Abstract
The LKB1 gene encodes a serine/threonine kinase mutated in Peutz−Jeghers cancer syndrome. Despite several proposed models for LKB1 function in development and in tumour suppression, the detailed molecular action of LKB1 remains undefined. Here, we report the identification and characterization of an LKB1-specific adaptor protein and substrate, STRAD (STe20 Related
