Abstract

While protein kinases are key components in multiple cellular processes, efficient identification of cognate in vivo substrates remains challenging. Here we describe a powerful method to screen potential substrates of protein kinases by partial transfer of proteins from a 2D-PAGE gel to a Western blot membrane. This approach allowed precise pinpointing of candidate substrate spots in the 2D gel, and identifying physiological substrates of protein kinases in Mycobacterium tuberculosis.
