CC   -!- FUNCTION: High oxygen affinity. Probably supplies oxygen needed for
CC       muscle activity.
CC   -!- SUBUNIT: Homodimer; disulfide-linked.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- TISSUE SPECIFICITY: Body wall globin is localized in cellular
CC       compartments belonging to the hypodermis, the dorsal, ventral and
CC       lateral cords, the nerve ring, and body wall muscle.
CC   -!- PTM: The N-terminus is blocked.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
