Target Information
STK4 (MST1) is a serine/threonine kinase involved in apoptosis and chromatin condensation. It acts as a stress-activated, pro-apoptotic kinase that, upon caspase cleavage, translocates to the nucleus to induce chromatin condensation and DNA fragmentation.
STK4 is a core component of the Hippo signaling pathway, regulating organ size and tumor suppression by controlling cell proliferation and apoptosis. In this pathway, STK3/MST2 and STK4/MST1, together with SAV1, phosphorylate and activate LATS1/2–MOB1 complex, which in turn phosphorylates and inactivates YAP1 and WWTR1/TAZ.
Phosphorylation of YAP1 by LATS2 inhibits its nuclear translocation, thereby regulating genes involved in cell proliferation, death, and migration. STK3/MST2 and STK4/MST1 are essential for repressing hepatocyte proliferation, preventing activation of adult liver stem cells, and inhibiting tumor formation.
