CC   -!- FUNCTION: Involved in oxygen transport from the lung to the various
CC       peripheral tissues.
CC   -!- FUNCTION: [Hemopressin]: Hemopressin acts as an antagonist peptide of
CC       the cannabinoid receptor CNR1. Hemopressin-binding efficiently blocks
CC       cannabinoid receptor CNR1 and subsequent signaling.
CC       {ECO:0000250|UniProtKB:P01946}.
CC   -!- SUBUNIT: Heterotetramer of two alpha chains and two beta chains.
CC   -!- TISSUE SPECIFICITY: Red blood cells.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
