Beta globin (HBB, β-globinprotin that, along with alpha globin (HBA), makes up the most common form of hemoglobin in adult humans.[1] The normal adult hemoglobin tetramer consists of two alpha chains and two beta chains.

Contents

Gene locus

The gene is located in the β-globin locus. Expression of beta globin and the neighboring globins in the β-globin locus is controlled by single locus control region (LCR).[2] The order of the genes in the beta-globin cluster is 5' - epsilongamma-Ggamma-Adeltabeta - 3'.[1]

Disease linkage

Mutant beta globin is responsible for the sickling of red blood cells seen in sickle cell anemia. Absence of beta chain causes beta-zero-thalassemia. Reduced amounts of detectable beta globin causes beta-plus-thalassemia.[1]

Interactions

HBB has been shown to interact with Hemoglobin, alpha 1.[3][4]
