Abstract:Bruton’s tyrosine kinase (BTK) functions in many types of immune cells and is a major chemotherapeutic target. BTK is activated at the plasma membrane and can dimerize through its pleckstrin-homology and contiguous tec-homology domains (the PH–TH module). The features that support dimerization of the PH–TH module are unique to BTK among the Tec kinases and appeared relatively recently in evolutionary history. Previous studies suggest that dimerization enhances kinase activity by promotingtransautophosphorylati… Show more
