The ced-8 gene encodes a homolog of the human putative membrane transporter XK; ced-8 is required for apoptosis to occur with normal speed during embryonic development.
Enables phospholipid scramblase activity. Involved in apoptotic process; embryo development; and engulfment of apoptotic cell. Located in plasma membrane. Is an ortholog of human XKR6 (XK related 6).
