The mammalian sterile 20-like (MST) kinases are central constituents of the evolutionary ancient canonical Hippo pathway regulating cell proliferation and survival. However, perhaps surprisingly, MST1 deficiency in human patients leads to a severe combined immunodeficiency syndrome with features of autoimmune disease. In line with this, Mst1-deficient mice exhibit severe defects in lymphocyte and neutrophil functions as well as disturbed intracellular vesicle transport. These findings spurred research on the noncanonical functions of MST1 in leukocytes. Here, we summarise the latest findings on this topic and discuss MST1 as a critical regulator of various leukocyte functions.
