HBB Gene (Protein Coding)

Hemoglobin Subunit Beta

GC11M005352
GIFtS:
45
The alpha (HBA) and beta (HBB) loci determine the structure of the 2 types of polypeptide chains in adult hemoglobin, Hb A. The normal adult hemoglobin tetramer consists of two alpha chains and two beta chains. Mutant beta globin causes sickle cell anemia. Absence of beta chain causes beta-zero-thalassemia. Reduced amounts of detectable beta globin causes beta-plus-thalassemia.... See more...

Summaries for HBB Gene

Entrez Gene Summary for HBB Gene

  • The alpha (HBA) and beta (HBB) loci determine the structure of the 2 types of polypeptide chains in adult hemoglobin, Hb A. The normal adult hemoglobin tetramer consists of two alpha chains and two beta chains. Mutant beta globin causes sickle cell anemia. Absence of beta chain causes beta-zero-thalassemia. Reduced amounts of detectable beta globin causes beta-plus-thalassemia. The order of the genes in the beta-globin cluster is 5'-epsilon -- gamma-G -- gamma-A -- delta -- beta--3'.

GeneCards Summary for HBB Gene

HBB (Hemoglobin Subunit Beta) is a Protein Coding gene. Diseases associated with HBB include Beta-Thalassemia and Sickle Cell Anemia. Among its related pathways are Folate Metabolism and Response to elevated platelet cytosolic Ca2+. Gene Ontology (GO) annotations related to this gene include iron ion binding and oxygen binding. An important paralog of this gene is HBD.

UniProtKB/Swiss-Prot Summary for HBB Gene

  • 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.

Post-translational modifications for HBB Gene

  • Glucose reacts non-enzymatically with the N-terminus of the beta chain to form a stable ketoamine linkage. This takes place slowly and continuously throughout the 120-day life span of the red blood cell. The rate of glycation is increased in patients with diabetes mellitus.
  • S-nitrosylated; a nitric oxide group is first bound to Fe(2+) and then transferred to Cys-94 to allow capture of O(2).
  • Acetylated on Lys-60, Lys-83 and Lys-145 upon aspirin exposure.
  • Glycosylation at Val2, Lys9, Lys18, Lys67, Lys121, and Lys145
  • Modification sites at PhosphoSitePlus

Polymorphic Variants from UniProtKB/Swiss-Prot for HBB Gene

HBB_HUMAN-P68871
Genetic variations in HBB are involved in resistance to malaria [MIM:611162]. Hemoglobin S (Hb S), which at homozygosity is responsible for sickle cell anemia, is not associated with any clinical abnormality when heterozygous. At heterozygosity, Hb S confers an increase in protection from life-threatening malaria. Additional variants conferring resistance against severe malaria are hemoglobin C (Hb C) and hemoglobin E (Hb E).

  • Heinz body anemias (HEIBAN) [MIM:140700]: Form of non-spherocytic hemolytic anemia of Dacie type 1. After splenectomy, which has little benefit, basophilic inclusions called Heinz bodies are demonstrable in the erythrocytes. Before splenectomy, diffuse or punctate basophilia may be evident. Most of these cases are probably instances of hemoglobinopathy. The hemoglobin demonstrates heat lability. Heinz bodies are observed also with the Ivemark syndrome (asplenia with cardiovascular anomalies) and with glutathione peroxidase deficiency. {ECO:0000269 PubMed:186485, ECO:0000269 PubMed:2599881, ECO:0000269 PubMed:6259091, ECO:0000269 PubMed:8704193}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
  • Beta-thalassemia (B-THAL) [MIM:613985]: A form of thalassemia. Thalassemias are common monogenic diseases occurring mostly in Mediterranean and Southeast Asian populations. The hallmark of beta-thalassemia is an imbalance in globin-chain production in the adult HbA molecule. Absence of beta chain causes beta(0)-thalassemia, while reduced amounts of detectable beta globin causes beta(+)-thalassemia. In the severe forms of beta-thalassemia, the excess alpha globin chains accumulate in the developing erythroid precursors in the marrow. Their deposition leads to a vast increase in erythroid apoptosis that in turn causes ineffective erythropoiesis and severe microcytic hypochromic anemia. Clinically, beta-thalassemia is divided into thalassemia major which is transfusion dependent, thalassemia intermedia (of intermediate severity), and thalassemia minor that is asymptomatic. {ECO:0000269 PubMed:12144064, ECO:0000269 PubMed:12149194, ECO:0000269 PubMed:15481886, ECO:0000269 PubMed:2399911, ECO:0000269 PubMed:6166632, ECO:0000269 PubMed:7693620}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Sickle cell anemia (SKCA) [MIM:603903]: Characterized by abnormally shaped red cells resulting in chronic anemia and periodic episodes of pain, serious infections and damage to vital organs. Normal red blood cells are round and flexible and flow easily through blood vessels, but in sickle cell anemia, the abnormal hemoglobin (called Hb S) causes red blood cells to become stiff. They are C-shaped and resembles a sickle. These stiffer red blood cells can led to microvascular occlusion thus cutting off the blood supply to nearby tissues. {ECO:0000269 PubMed:1195378, ECO:0000269 PubMed:13464827, ECO:0000269 PubMed:16001361, ECO:0000269 PubMed:24100324, ECO:0000269 Ref.10}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Beta-thalassemia, dominant, inclusion body type (B-THALIB) [MIM:603902]: An autosomal dominant form of beta thalassemia characterized by moderate anemia, lifelong jaundice, cholelithiasis and splenomegaly, marked morphologic changes in the red cells, erythroid hyperplasia of the bone marrow with increased numbers of multinucleate red cell precursors, and the presence of large inclusion bodies in the normoblasts, both in the marrow and in the peripheral blood after splenectomy. {ECO:0000269 PubMed:1971109}. Note=The disease is caused by mutations affecting the gene represented in this entry.
