May function as an adapter protein in a pathway that mediates recognition and phagocytosis of apoptotic cells during normal development. Promotes engulfment of cells at both early and late stages of apoptosis. Required for actin reorganization around apoptotic cells. Plays a role in protecting dopaminergic neurons from oxidative stress-induced degeneration (PubMed:29346382). Homodimer. Interacts with ced-1. Detected in gonadal sheath cells. Belongs to the ced-6 family.
