CC   -!- FUNCTION: Involved in oxygen transport from gills to the various
CC       peripheral tissues. {ECO:0000269|PubMed:12118003}.
CC   -!- SUBUNIT: Hb1 is a heterotetramer of two alpha-1 chains and two beta-1
CC       chains; Hb2 is a heterotetramer of two alpha-2 chains and two beta-1
CC       chains.
CC   -!- TISSUE SPECIFICITY: Red blood cells. {ECO:0000269|PubMed:12118003}.
CC   -!- MISCELLANEOUS: Hb1 and Hb2 display a low, effector-enhanced Bohr effect
CC       and no Root effect.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
