General annotation (Comments)

Function	Involved in oxygen transport from the lung to the various peripheral tissues.
Subunit structure	Heterotetramer of two alpha chains and two beta chains.
Tissue specificity	Red blood cells.
Miscellaneous	Two kinds of alpha-3 chains were found in one gorilla. An Asx replaces one Ser (at position 131, 133, or 138) in the tryptic peptide comprising residues 128-139.
Sequence similarities	Belongs to the globin family.
