General description

Conalbumin, also referred to as ovotransferrin, is encoded by the avian transferrin gene in the oviduct. It is a monomeric glycoprotein consisting of 686 amino acids and is a member of transferrin family. Conalbumin is one among the abundant proteins present in the chicken egg white.

Application

Conalbumin has been used:
  • as a constituent of Leibovitz 15 (L15) medium involved in preparation of primary neuronal cultures
  • to study its adsorption property on a metal surface in the presence of an external electric potential
  • to determine its adsorption isotherms in anion exchange chromatography by multivariate analysis

Biochem/physiol Actions

Conablumin (aka ovotransferrin) is a glycoprotein derived from egg white with a sequence similar to serum transferrin, but with a different glycosylation pattern. It is a strong iron binder with antiviral and antibacterial activities.
Conalbumin facilitates the transport of iron to the developing embryo. It exhibits anti-microbial activity thus, conalbumin is used in various applications such as infant formula ingredient, a food additive, and an antimicrobial agent for enhancing animal health. In addition, it also acts as an antifungal, antiviral, anticancer, antioxidative, antihypertensive and immunoregulatory agent.
