Protein kinases function as key signaling hubs in the intricate network of biochemical signaling processes in the living cell. More than two‐thirds of the human proteome is estimated to be phosphorylated at ~960,000 phosphosites, which makes it challenging to identify the direct contribution of any desired kinase in generating this phosphoproteome. In this review, we discuss some of the methods that have been developed over the years for global identification of kinase substrates. The methods are essentially categorized into two classes, namely, (i) direct tagging of kinase substrates and (ii) indirect phosphoproteomics‐based approaches. We discuss the advantages and limitations entailed to each of the method introduced, with a special emphasis on the analog‐sensitive (as) kinase approach method. © 2019 IUBMB Life, 71(6):721–737, 2019
