Serine/threonine-protein kinase, which plays a role in regulating allophagy, an autophagic process in which paternal organelles, including mitochondria and membranous organelles, are degraded in embryos. Phosphorylates the allophagy receptor allo-1, which is required for allophagy. ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Interacts with allo-1 (via N-terminus); the interaction is direct. Localizes to cytoplasmic puncta in oocytes. After fertilization, localizes to paternal organelles during meiosis I and meiosis II. Co-localizes with allo-1 in embryos and oocytes. Expressed in oocytes. RNAi-mediated knockdown results in defective clearance of paternal mitochondria and impaired accumulation of the autophagosome marker lgg-1 in 1-cell stage embryos. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
