abstract
Ovalbumin is a major protein in the egg white. It is a monomeric phosphor glycoprotein with a known complete amino acid sequence of 386 residues. Due to its structural similarities with the serine protease inhibitors (Ser PIns), it is included in the serpin super family, although it lacks inhibitory activities. The size of the entire ovalbumin gene in poultry is approximately 7.6 kb of DNA with 7 exons and 6 introns, in order to code for mRNA of 1859 nucleotides. Tubular gland cells of magnum are responsible for the production of ovalbumin protein. Ovalbumin gene in poultry have been found polymorphic in various populations in various parts of gene including coding sequence, promoter region etc., ovalbumin serve as a source of amino acid and may also have a more active/direct function on developing tissues and believed to play a crucial role in bio mineralization.
