CC -!- FUNCTION: Serves as a reserve supply of oxygen and facilitates the
CC movement of oxygen within muscles.
CC -!- MISCELLANEOUS: Marmoset, woolly monkey, and squirrel monkey have a
CC minor myoglobin component that appears to differ from each major
CC component in having Phe-Lys preceding position 2.
CC -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00238}.
