CC   -!- FUNCTION: Could be the homolog of mammalian Bcl-W.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- DEVELOPMENTAL STAGE: Developmental regulation only occurs in the brain
CC       of mid-metamorphosic to post-metamorphosic tadpoles and adults, where
CC       an increase of several fold has been observed.
CC   -!- SIMILARITY: Belongs to the Bcl-2 family. {ECO:0000305}.
