CC peripheral tissues. {ECO:0000269|PubMed:16717098, ECO:0000305}.
CC -!- SUBUNIT: Hb 2 is a heterotetramer of two alpha-2 and two beta-2 chains.
CC Hb 3 is a heterotetramer of two alpha-1 and two beta-2 chains.
CC {ECO:0000269|PubMed:16717098}.
CC -!- TISSUE SPECIFICITY: Red blood cells. {ECO:0000305}.
CC -!- MISCELLANEOUS: Hb 3 displays a Bohr effect, which is enhanced by
CC organophosphates, and a Root effect, which is enhanced by ATP.
CC -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00238}.
