FHL2 and esophageal squamous cell carcinoma: TAB182 further recruits FHL2 and forms a TAB182-FHL2-β-catenin complex allowing for efficient FHL2-mediated β-catenin nucleus translocation by enhancing the association between FHL2 and β-catenin, and this is dependent on the RXXPDG motif of TAB182 in ESCC cells.
