LIMK1 as a Novel Kinase of β-Catenin Promotes Esophageal Cancer Metastasis by Cooperating With CDK5.

ABSTRACT: Metastasis is a major cause of cancer deaths, but the underlying molecular mechanisms remain largely unknown. Esophageal squamous cell carcinoma (ESCC) is a highly aggressive cancer with poor survival, yet the key kinases driving ESCC metastasis and their biological function have not been fully discovered. Here, a kinase-substrate map of metastatic ESCC is presented for the first time by conducting a phosphoproteomics analysis of 60 clinical specimens. By further consolidating data with CRISPR/Cas9 functional screening, LIM domain kinase 1 (LIMK1) is identified as a novel kinase of β-catenin. The in vitro and in vivo experiments demonstrated that LIMK1 cooperates with Cyclin-dependent kinase 5 (CDK5) to promote cancer metastasis in a phosphorylation-dependent manner. Mechanistically, LIMK1
