The three isoforms of protein kinase D (PKD) have important but often redundant roles in cell signalling. Here the authors show, by generating PKD2/3 double-deficient mice, that PKD is essential for TCR signalling in thymocytes, and identify SHP-1 as a PKD target critical for development of CD4+T cells.
