Function

Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed:19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017).

Activity summary

Albumin also known as ALB is a major plasma protein with a molecular mass of approximately 66.5 kDa. It predominantly gets synthesized in the liver and found abundantly in blood plasma. Albumin serves multiple functions including maintaining osmotic pressure and acting as a carrier protein for various endogenous substances like hormones fatty acids and bilirubin.

Biological function summary

Albumin plays a critical role in transporting small molecules like metabolites and drugs through the circulatory system. It is not a part of any complex but functions independently to bind transport and release various ligands. Albumin's affinity for hydrophobic molecules makes it essential for they to be solubilized in blood for proper metabolism and excretion.

Pathways

More than five binding sites on albumin facilitate its role in the fatty acid metabolism and renin-angiotensin system pathways. In fatty acid metabolism albumin interacts with transport proteins carrying fatty acids to tissues for energy production. Additionally during the renin-angiotensin system albumin modulates blood pressure through its interaction with angiotensin II which can influence vasoconstriction.

Associated diseases and disorders

Researchers link albumin with nephrotic syndrome and liver cirrhosis. In nephrotic syndrome low levels of albumin (albumin low) can cause edema due to imbalanced osmotic pressure. In liver cirrhosis a reduction in albumin synthesis signifies liver damage. Albumin's interaction with proteins like angiotensin II correlates with complications such as hypertension further establishing the protein's role in health and disease contexts.
