CC   -!- FUNCTION: Involved in oxygen transport from the lung to the various
CC       peripheral tissues.
CC   -!- SUBUNIT: Heterotetramer of two alpha chains and two beta chains.
CC   -!- TISSUE SPECIFICITY: Red blood cells.
CC   -!- POLYMORPHISM: There are two alleles. The sequence shown is that of
CC       beta-S. {ECO:0000269|PubMed:4063068}.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
