CC   -!- FUNCTION: Serves as a reserve supply of oxygen and facilitates the
CC       movement of oxygen within muscles.
CC   -!- MISCELLANEOUS: Some amides were assigned by electrophoretic mobility or
CC       by homology.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
