The globins are a superfamily of heme-containing globular proteins, involved in binding and/or transporting oxygen. These proteins all incorporate the globin fold, a series of eight alpha helical segments .
Schematic representation of a protein electrophoresis gel. All globulins fall into one of the following three categories : Alpha globulins; Beta globulins; Gamma globulins (one group of gamma globulins is the immunoglobulins, which are also known as "antibodies")
3-dimensional structure of hemoglobin, a globular protein.. In biochemistry, globular proteins or spheroproteins are spherical ("globe-like") proteins and are one of the common protein types (the others being fibrous, disordered and membrane proteins).
Hemoglobin, erythrocruorin, and chlorocruorin are all globins, iron-heme proteins with a common core. Their color comes from the absorption spectra of heme with Fe 2+. Erythrocruorin and chlorocruorin are closely related giant globins found used by some invertebrates. Chlorocruorin has a special heme group, giving it different colors.
HBB protein is produced by the gene HBB which is located in the multigene locus of β-globin locus on chromosome 11, specifically on the short arm position 15.4. Expression of beta globin and the neighbouring globins in the β-globin locus is controlled by single locus control region (LCR), the most important regulatory element in the locus located upstream of the globin genes.
