Ovalbumin (abbreviated OVA [1]) is the main protein found in egg white, making up approximately 55% of the total protein. [2] Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. [ 3 ]
Ovalbumin is the most abundant protein in albumen. Classed as phosphoglycoprotein, during storage, it converts into s-ovalbumin (5% at the time of laying) and can reach up to 80% after six months of cold storage. Ovalbumin in solution is heat-resistant. Denaturation temperature is around 84 °C, but it can be easily denatured by physical stresses.
Ovalbumin is a storage protein in egg white (albumen). It is a serpin. Lactalbumin, or whey protein, is a protein fraction of milk. It is mainly Beta-lactoglobulin, although serum albumin also comprises a small part of it. Some plant seeds, including hemp, encode "2S albumins". These are named for their egg-like coagulation property.
The chicken ovalbumin upstream promoter transcription factor (COUP-TFs) proteins are members of the nuclear receptor family of intracellular transcription factors. [1] There are two variants of the COUP-TFs, labeled as COUP-TFI and COUP-TFII encoded by the NR2F1 and NR2F2 genes respectively. COUP-TFs play critical roles in the development of ...

Some storage proteins store amino acids. Storage proteins' amino acids are used in embryonic development of animals or plants. Two amino acid storage proteins in animals are casein and ovalbumin. Seeds, particularly of leguminous plants, contain high concentrations of storage proteins. Up to 25 percent of the dry weight of the seed can be ...
A critical portion of the molecule, the reactive center loop connects beta sheets A and C. Protease inhibitor-10 (PI10; SERPINB10) is a member of the ov-serpin subfamily, which, relative to the archetypal serpin PI1, is characterized by a high degree of homology to chicken ovalbumin, lack of N- and C-terminal extensions, absence of a signal ...
Coup (chicken ovalbumin upstream promoter) transcription factor binds to the ovalbumin promoter and, in conjunction with another protein stimulates initiation of transcription. [ 7 ] [ 8 ] COUP-TF1 binds to both direct repeats and palindromes of the 5'-AGGTCA-3' motif.
