CC   -!- FUNCTION: Antiapoptotic protein which protects cells uniquely from Fas-
CC       induced apoptosis. Regulates Fas-mediated apoptosis in neurons by
CC       interfering with caspase-8 activation. Plays a role in cerebellar
CC       development by affecting cerebellar size, internal granular layer (IGL)
CC       thickness, and Purkinje cell (PC) development (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with FAS/TNFRSF6 and BAX. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}. Membrane raft {ECO:0000250}. Postsynaptic cell
CC       membrane {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the BI1 family. LFG subfamily. {ECO:0000305}.
