Predicted to enable molecular adaptor activity and protein kinase binding activity. Predicted to be involved in several processes, including autophagy of mitochondrion; macroautophagy; and piecemeal microautophagy of the nucleus. Predicted to act upstream of or within several processes, including liver development; positive regulation of cell size; and regulation of signal transduction. Predicted to be located in several cellular components, including nuclear membrane; phagophore assembly site; and vacuole. Predicted to be part of Atg1/ULK1 kinase complex. Predicted to be active in phagophore assembly site membrane. Predicted to be extrinsic component of membrane. Human ortholog(s) of this gene implicated in breast cancer. Orthologous to human RB1CC1 (RB1 inducible coiled-coil 1). [provided by Alliance of Genome Resources, Apr 2022]
