MeSH

A superfamily of proteins containing the globin fold which is composed of 6-8 alpha helices arranged in a characterstic HEME enclosing structure.

A member of the beta-globin family. In humans, epsilon-globin is encoded in the beta-globin gene cluster located on CHROMOSOME 11. Two epsilon-globin chains combine with two ZETA-GLOBIN chains to form the embryonic hemoglobin Gower I or two epsilon-globin chains combine with two ALPHA-2 GLOBIN chains to form the embryonic hemoglobin Gower II.

A member of the beta-globin family. In humans, delta-globin is encoded in the beta-globin gene cluster located on CHROMOSOME 11. Two delta-globin chains along with two alpha-globin chains form HEMOGLOBIN A2 which makes up about 3% of the HEMOGLOBIN in adults.

Members of the beta-globin family. In humans, two non-allelic types of gamma-globin - A gamma and G gamma are encoded in the beta-globin gene cluster on CHROMOSOME 11. Two gamma-globin chains combine with two ZETA-GLOBIN chains to form the embryonic hemoglobin Portland. Fetal HEMOGLOBIN F is formed from two gamma-globin chains combined with two ALPHA-GLOBIN chains.

Members of the beta-globin family. In humans, they are encoded in a gene cluster on CHROMOSOME 11. They include epsilon-globin, gamma-globin, delta-globin and beta-globin. There is also a pseudogene of beta (theta-beta) in the gene cluster. Adult HEMOGLOBIN is comprised of two ALPHA-GLOBIN chains and two beta-globin chains.

A member of the alpha-globin family. In humans, zeta-globin is encoded in the alpha-globin gene cluster located on CHROMOSOME 16. Two zeta-globin chains combine with two EPSILON GLOBIN chains to form the embryonic HEMOGLOBIN Gower 1.

Year introduced: 2009

Members of the alpha-globin family. In humans, they are encoded in a gene cluster on CHROMOSOME 16. They include zeta-globin and alpha-globin. There are also pseudogenes of zeta (theta-zeta) and alpha (theta-alpha) in the cluster. Adult HEMOGLOBIN is comprised of 2 alpha-globin chains and 2 beta-globin chains.
