Kinase: MST2 serine/threonine kinase 3 (STE20 homolog, yeast)

Group: STE      Family: STE20      Subfamily: MST

Description: serine/threonine kinase 3 (STE20 homolog, yeast)

Gene Symbol: STK3

Synonyms: FLJ90748, KRS1, MST2

UniprotKB/SwissProt: STK3_HUMAN (Q13188)

Function: Stress-activated, pro-apoptotic kinase which, following caspase-cleavage, enters the nucleus and induces chromatin condensation followed by internucleosomal DNA fragmentation. Phosphorylates NKX2-1 (By similarity). Phosphorylates and activates LATS1 and LATS2.

Subcellular Localization: Cytoplasm (By similarity). Nucleus (By similarity). Note=The caspase-cleaved form cycles between nucleus and cytoplasm (By similarity).
