The function of HBB (hemoglobin subunit beta, Ensembl gene identifier ENSG00000244734) is as follows. Involved in oxygen transport from the lung to the various peripheral tissues. . LVV-hemorphin-7 potentiates the activity of bradykinin, causing a decrease in blood pressure. [Spinorphin]: Functions as an endogenous inhibitor of enkephalin-degrading enzymes such as DPP3, and as a selective antagonist of the P2RX3 receptor which is involved in pain signaling, these properties implicate it as a regulator of pain and inflammation.
