Serine/threonine-protein kinase that acts as a mediator of cell growth (, ). Modulates apoptosis (, ). In association with STK24 negatively regulates Golgi reorientation in polarized cell migration upon RHO activation . Phosphorylates ATG4B at 'Ser-383', thereby increasing autophagic flux .
Subcellular locations: Cytoplasm, Golgi apparatus
Colocalized with RIPOR1 in the Golgi of serum-starved cells and relocated to cytoplasmic punctae, probably vesicular compartments, along with RIPOR1 upon serum stimulation in a Rho- and PDCD10-dependent manner .
