General annotation (Comments)

Function	Stress-activated, pro-apoptotic kinase which, following caspase-cleavage, enters the nucleus and induces chromatin condensation followed by internucleosomal DNA fragmentation. Phosphorylates 'Ser-14' of histone H2B during apoptosis. Phosphorylates FOXO3 upon oxidative stress, which results in its nuclear translocation and cell death initiation. Ref.2 Ref.6 Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium.
Enzyme regulation	Inhibited by the C-terminal non-catalytic region. Activated by caspase-cleavage. Full activation also requires homodimerization and autophosphorylation of Thr-183. Ref.6 Ref.10
Subunit structure	Homodimer; mediated via the coiled-coil region. Interacts with NORE1, which inhibits autoactivation. Interacts with and stabilizes SAV1. Interacts with RASSF1, which leads to enzyme activation. Interacts with FOXO3. Ref.6 Ref.10 Ref.11 Ref.12 Ref.13
Subcellular location	Cytoplasm. Nucleus. Note: The caspase-cleaved form cycles between the nucleus and cytoplasm. Ref.7 Ref.8
Tissue specificity	Ubiquitously expressed.
Post-translational modification	Autophosphorylated on serine and threonine residues. Ref.9 Ref.10 Ref.14 Ref.15 Ref.16
Sequence similarities	Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily. Contains 1 protein kinase domain. Contains 1 SARAH domain.
