Casoplatelin; Kappa-casein stabilizes micelle formation, preventing casein precipitation in milk. Casoplatelin inhibits platelet aggregation; Belongs to the kappa-casein family.

Alpha-lactalbumin; Regulatory subunit of lactose synthase, changes the substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme. This enables LS to synthesize lactose, the major carbohydrate component of milk. In other tissues, galactosyltransferase transfers galactose onto the N- acetylglucosamine of the oligosaccharide chains in glycoproteins; Belongs to the glycosyl hydrolase 22 family.

Alpha-S2-casein; Important role in the capacity of milk to transport calcium phosphate; Belongs to the alpha-casein family.

Beta-lactoglobulin; Primary component of whey, it binds retinol and is probably involved in the transport of that molecule; Belongs to the calycin superfamily. Lipocalin family.

Glycosylation-dependent cell adhesion molecule 1.

Lactotransferrin; Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. Lactoferricin B is an antimicrobial peptide. Inhibits the growth of Gram-negative and Gram-positive bacteria.

Chymosin; Chymosin is synthesized in the mucosa of the abomasum (fourth stomach) of young (unweaned) ruminants. The enzyme hydrolyzes casein to paracasein; Belongs to the peptidase A1 family.

Serum albumin; Serum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (By similarity). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (Probable). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner. The sh [...]

Butyrophilin subfamily 1 member A1; May function in the secretion of milk-fat droplets. May act as a specific membrane-associated receptor for the association of cytoplasmic droplets with the apical plasma membrane. Inhibits the proliferation of CD4 and CD8 T-cells activated by anti-CD3 antibodies, T-cell metabolism and IL2 and IFNG secretion (By similarity). Belongs to the immunoglobulin superfamily. BTN/MOG family.
