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 (PubMed:18077343). Hemopressin-binding efficiently blocks cannabinoid receptor CNR1 and subsequent signaling (PubMed:18077343).

- Activity summary
Hemoglobin subunit alpha also known as alpha-globin is a component of the hemoglobin protein complex which plays an important role in oxygen transport within the blood. Alpha-globin has an approximate molecular weight of 15.1 kDa and is expressed highly in the red blood cells. It is part of the hemoglobin tetramer along with two beta subunits each one containing an iron-bound heme group. Variants of the alpha chain can be studied using hemoglobin peptides or denatured hemoglobin samples. Researchers can further analyze the alpha hemoglobin using methods like SDS-PAGE or alpha ELISA assays.
- Biological function summary
Hemoglobin subunit alpha forms an important part of the hemoglobin complex facilitating the binding and release of oxygen molecules as blood circulates in the body. Alpha hemoglobin ensures efficient loading of oxygen in the lungs and unloading in tissues maintaining cellular respiration. The subunit plays a structural role as well stabilizing the hemoglobin tetramer for optimal function. Its ability to carry oxygen depends on the cooperative interaction between its alpha and beta globin counterparts.
- Pathways
Hemoglobin subunit alpha operates predominantly within the oxygen transport pathway which is essential to meet the metabolic demands of cells. It also links to pathways involving iron metabolism given its coordination with heme groups. Alpha hemoglobin interacts cooperatively with proteins such as beta-globin to ensure efficient oxygen delivery. This interplay is highlighted when examining hemoglobin biosynthesis and breakdown pathways.
- Associated diseases and disorders
Alpha-globin is linked to conditions like alpha-thalassemia and sickle cell disease. These disorders result from mutations in the hemoglobin alpha or beta subunits leading to imbalanced globin production or abnormal hemoglobin structures. Alpha thalassemia is connected with unequal production of globin chains affecting hemoglobin stability while beta-globin mutations lead to sickle cell disease with altered oxygen delivery. Anti-hemoglobin antibodies might help in researching these conditions allowing a better understanding of molecular changes and potential therapeutic targets.
