CC -!- FUNCTION: Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones,
CC bilirubin and drugs. Its main function is the regulation of the
CC colloidal osmotic pressure of blood. Major zinc transporter in plasma,
CC typically binds about 80% of all plasma zinc (By similarity). Major
CC calcium and magnesium transporter in plasma, binds approximately 45% of
CC circulating calcium and magnesium in plasma (By similarity).
CC Potentially has more than two calcium-binding sites and might
CC additionally bind calcium in a non-specific manner (By similarity). The
CC shared binding site between zinc and calcium at residue Asp-272
CC suggests a crosstalk between zinc and calcium transport in the blood
CC (By similarity). The rank order of affinity is zinc > calcium >
CC magnesium (By similarity). Binds to the bacterial siderophore
CC enterobactin and inhibits enterobactin-mediated iron uptake of E.coli
CC from ferric transferrin, and may thereby limit the utilization of iron
CC and growth of enteric bacteria such as E.coli (By similarity). Does not
CC prevent iron uptake by the bacterial siderophore aerobactin (By
CC similarity). {ECO:0000250|UniProtKB:P02768,
CC ECO:0000250|UniProtKB:P02769}.
CC -!- SUBUNIT: Interacts with FCGRT; this interaction regulates ALB
CC homeostasis (By similarity). Interacts with TASOR (By similarity). In
CC plasma, occurs in a covalently-linked complex with chromophore-bound
CC alpha-1-microglobulin; this interaction does not prevent fatty acid
CC binding to ALB. {ECO:0000250|UniProtKB:P02768,
CC ECO:0000250|UniProtKB:P07724}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Plasma.
CC -!- PTM: Phosphorylated by FAM20C in the extracellular medium.
CC {ECO:0000250|UniProtKB:P02768}.
CC -!- SIMILARITY: Belongs to the ALB/AFP/VDB family. {ECO:0000255|PROSITE-
CC ProRule:PRU00769}.
