CC -!- FUNCTION: Serine/threonine-protein kinase that acts as a mediator of
CC cell growth. Modulates apoptosis. In association with STK24 negatively
CC regulates Golgi reorientation in polarized cell migration upon RHO
CC activation. Phosphorylates ATG4B at 'Ser-383', thereby increasing
CC autophagic flux. {ECO:0000250|UniProtKB:Q9P289}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q9Y4P1};
CC -!- ACTIVITY REGULATION: Interaction with Golgi matrix protein GOLGA2 leads
CC to autophosphorylation on Thr-178, possibly as a consequence of
CC stabilization of dimer formation. May also be activated by C-terminal
CC cleavage (By similarity). {ECO:0000250|UniProtKB:Q9P289}.
CC -!- SUBUNIT: Homodimer. Interacts with PDCD10. Interacts with GOLGA2.
CC Interacts with CTTNBP2NL. Interacts with RIPOR1 (via C-terminus); this
CC interaction occurs in a PDCD10-dependent and Rho-independent manner.
CC Interacts with PDCD10; this interaction is required for the association
CC of STK26 with RIPOR1. {ECO:0000250|UniProtKB:Q9P289}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9P289}. Golgi
CC apparatus {ECO:0000250|UniProtKB:Q9P289}. Note=Colocalized with RIPOR1
CC in the Golgi of serum-starved cells and relocated to cytoplasmic
CC punctae, probably vesicular compartments, along with RIPOR1 upon serum
CC stimulation in a Rho- and PDCD10-dependent manner.
CC {ECO:0000250|UniProtKB:Q9P289}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. STE Ser/Thr
CC protein kinase family. STE20 subfamily. {ECO:0000305}.
