  • Function
    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.
  • Tissue specificity
  • Involvement in disease
    Defects in ALB are a cause of familial dysalbuminemic hyperthyroxinemia (FDH) [MIM:103600]. FDH is a form of euthyroid hyperthyroxinemia that is due to increased affinity of ALB for T(4). It is the most common cause of inherited euthyroid hyperthyroxinemia in Caucasian population.
  • Sequence similarities
    Belongs to the ALB/AFP/VDB family.
    Contains 3 albumin domains.
  • Post-translational
    Kenitra variant is partially O-glycosylated at Thr-620. It has two new disulfide bonds Cys-600 to Cys-602 and Cys-601 to Cys-606.
    Glycated in diabetic patients.
    Phosphorylation sites are present in the extracelllular medium.
    Acetylated on Lys-223 by acetylsalicylic acid.
