애플리케이션
α-Lactalbumin from bovine milk has been used:
- in indirect enzyme-linked immunosorbent assay (ELISA) and competitive ELISA methods
- in binding of Hsp90 and HSJ1b analysis
- to inhibit the lysozyme CAP-RAST assay
생화학적/생리학적 작용
α-Lactalbumin is the cheif protein in human milk. It consists of a single polypeptide chain with 8 cysteines which form disulfide bridges. α-Lactalbumin binds several metal ions, including calcium, which is thought to play a role in the regeneration of native α-lactalbumin from the reduced, denatured form. α-Lactalbumin also has a distinct zinc binding site that is thought to play a role in the binding of the lactose synthase complex.The mature protein consists of 123 amino acid residues (14 kD), and it has a three-dimensional structure with 1.7 Angstrom resolution, demonstrating four α-helices and a triple stranded antiparallel β-sheet.
Alters the substrate specificity of galactosyltransferase to increase the rate of lactose formation; the complex of galactosyltransferase and α-lactalbumin is called lactose synthase.
Alters the substrate specificity of galactosyltransferase to increase the rate of lactose formation; the complex of galactosyltransferase and α-lactalbumin is called lactose synthase. Site-directed mutagenesis of Asp87 or Asp88 to Ala completely abolishes the strong calcium binding affinity and reduces the stimulation of lactose synthase to <3.5% of the maximal rate.

An α-lactalbumin-oleic acid (α-LA-OA) complex has exhibited selective antitumor activity in animal models and clinical trials. Although apoptosis and autophagy are activated and the functions of several organelles are disrupted in response to α-LA-OA, the detailed antitumor mechanism remains unclear.

Lymphatic vascular permeability prevents lymph leakage that is associated with lymphedema, lymphatic malformations, obesity, and inflammation. However, the molecular control of lymphatic permeability remains poorly understood. Recent studies have suggested that adherens junctions and vesicle transport may be involved in
