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}.
