Predicted to enable protein kinase regulator activity. Predicted to be involved in mitophagy; piecemeal microautophagy of the nucleus; and protein localization to phagophore assembly site. Predicted to act upstream of or within autophagosome assembly. Predicted to be located in cytoplasm. Predicted to be part of Atg1/ULK1 kinase complex. Predicted to be active in autophagosome; cytosol; and phagophore assembly site. Orthologous to human ATG13 (autophagy related 13).
