CC -!- FUNCTION: Functions as a cell surface receptor and performs
CC physiological functions on the surface of neurons relevant to neurite
CC growth, neuronal adhesion and axonogenesis.
CC {ECO:0000256|RuleBase:RU367156}.
CC -!- FUNCTION: N-APP binds TNFRSF21 triggering caspase activation and
CC degeneration of both neuronal cell bodies (via caspase-3) and axons
CC (via caspase-6). {ECO:0000256|ARBA:ARBA00003551}.
CC -!- FUNCTION: The gamma-CTF peptides as well as the caspase-cleaved
CC peptides, including C31, are potent enhancers of neuronal apoptosis.
