Function
function
Involved in oxygen transport from the lung to the various peripheral tissues.
Hemopressin
Hemopressin acts as an antagonist peptide of the cannabinoid receptor CNR1. Hemopressin-binding efficiently blocks cannabinoid receptor CNR1 and subsequent signaling.
Miscellaneous
Gives blood its red color.
