Autophagy receptor, which is required for allophagy, an autophagic process in which paternal organelles, including mitochondria and membranous organelles, are degraded in early embryos. After fertilization, recruited to ubiquitin-modified paternal organelles and is required for the formation of autophagosomes around the paternal organelles. Also plays a role in the regulation of autophagy in germ cells. Self-associates. Interacts (via N-terminus) with ikke-1; the interaction is direct. Interacts (via the LIR motif) with lgg-1. Interacts (via C-terminus) with ubiquitinated proteins. Localizes to cytoplasmic puncta in oocytes and to paternal organelles in 1-stage embryos. After fertilization, localizes around paternal mitochondria and ubiquitinated membranous organelles at metaphase phase of meiosis I, before lgg-1 is recruited. Also, localizes to paternal organelles during meiosis II. Co-localizes with ikke-1 in embryos and oocytes. Expressed in oocytes, but not in spermatozoa. The C-terminal region is required for localization to paternal organelles. Phosphorylation on Thr-74 by ikke-1 is required for allophagic function.
