Hoffbrand's Essential Haematology, 7th Edition

Haemoglobin A HbA , the principle haemoglobin of adults, consists of a pair each of alpha and of beta polypeptide chains and its structure is designated as Foetal haemoglobin HbF , the predominant haemoglobin in foetal life, contains a pair of alpha and a pair of gamma chains. Two types of chains are distinguished, G and A, which have different amino acids either glycine or alanine at position Thus, HbF is heterogeneous and contains 22 Gly and 22 Ala.

With foetal development, synthesis of zeta and epsilon chains is replaced by that of and chains, respectively. After birth, production of chains switches to that of and delta chains. Structure of globin genes: Normal haemoglobin is a tetramer composed of a pair of -like and a pair of -like polypeptide chains.

Each chain is linked to one molecule of haem.

The -like polypeptide chains and and -like polypeptide chains , , , and are encoded by - and -globin gene clusters on chromosomes 16 and 11, respectively. The order of genes in -globin gene cluster from 5 to 3 end is The order of genes in -globin gene cluster from 5 to 3 end is -G-A Fig.

Open boxes represent pseudogenes while filled boxes represent active genes. Normal genotype is shown below each gene cluster Figure 1.

A pseudogene contains sequences similar to a functional gene but is rendered inactive due to mutation during evolutionary process. In humans, autosomal chromosomes occur in pairs.

As each member of chromosome 16 has two gene loci a locus refers to specific physical position of a gene on chromosome , there are total four genes. However, there is only one globin gene locus on chromosome 11, and therefore genes are two in number. Genes are the base sequences, which are present along the DNA strands and are necessary for the formation of a protein. The different functional areas of a globin gene are: 1.

Exons and introns: The regions of DNA strand which encode amino acids in the protein product are known as exons while non-coding regions which interrupt the coding sequences are known as introns or intervening sequences. Each globin gene contains three exons and two introns.

Splice junction sequences: These are sequences at the junction of exons and introns and are required for precise splicing or removal of introns during the formation of mRNA. Promoter: The promoter region is present towards 5 end of the gene and contains sequences to which the RNA polymerase binds; it is necessary for correct initiation of transcription. Steps in the synthesis of globin: Globin synthesis involves three stepstranscription, processing of mRNA, and translation Fig.

Binding of RNA polymerase to the promoter is essential for accurate initiation of transcription. Transcription continues through exons and introns and when a chain terminating sequence is encountered, RNA polymerase gets separated from the DNA strand. A cap structure modified nucleotides is added at the 5 end of mRNA; though the exact role is unknown, capping appears to be necessary for initiation of translation.

At the 3 end a poly-A tail consisting of about adenylic acid residues is added.
