Predicted to enable protein homodimerization activity. Predicted to be involved in positive regulation of autophagosome maturation; response to interferon-gamma; and xenophagy. Predicted to act upstream of or within autophagy. Predicted to be located in cytosol; intracellular membrane-bounded organelle; and perinuclear region of cytoplasm. Predicted to be active in PML body and autophagosome. Orthologous to human CALCOCO2 (calcium binding and coiled-coil domain 2). [provided by Alliance of Genome Resources, Apr 2022]
