WebMay 27, 2011 · One common example of complex multigene families is the globin genes in humans. The genes for alpha and beta chains of the mammalian hemoglobin molecule are coded by multigene families on chromosomes 16 and 11 respectively. These sequences though similar code for different chains are different. The sequence similarity between … WebThe beta-globin gene family located on chromosome 11 is shown in the figure below and consists of five functional genes (blue boxes) and two pseudogenes (diagonal lines). …

WebMutations in globin genes cause thalassemias. Beta thalassemia affects one or both of the β-globin genes. These mutations result in the impaired synthesis of the β-globin protein … Globins evolved from a common ancestor and can be divided into three lineages: Family M (for myoglobin-like) or F (for FHb-like), which has a typical 3/3 fold. Family S (for sensor-like), again with a 3/3 fold. Family T (for truncated), with a 2/2 fold All subfamilies can be chimeric, single-domain, or tandemly … See more 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. Two prominent … See more Globin superfamily members share a common three-dimensional fold. This 'globin fold' typically consists of eight alpha helices, … See more Human genes encoding globin proteins include: • CYGB • HBA1, HBA2, HBB, HBD, HBE1, HBG1, HBG2, HBM, HBQ1, HBZ, MB See more • Biology portal • C-rich stability element • Globular protein • Hemoglobin See more • Leghaemoglobin InterPro: IPR001032 • Myoglobin InterPro: IPR002335 • Erythrocruorin InterPro: IPR002336 See more The globin fold (cd01067) also includes some non-haem proteins.

WebJun 30, 2016 · This beta-globin gene was isolated from a beta + thalassemic patient and differs from the normal beta-globin genes by only a single point mutation within the first intron. The beta + thalassemic and the normal beta-globin genes were cloned into an SV40-pBR328 vector and introduced into HeLa cells by calcium phosphate coprecipitation. WebMutations in globin genes cause thalassemias. Beta thalassemia affects one or both of the β-globin genes. These mutations result in the impaired synthesis of the β-globin protein portion, a component of Hb, thus causing anaemia. The genetic defect usually is a missense or nonsense mutation in the β-globin gene, although occasional defects ...
