Disease

ALBU_HUMAN 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.^[1] ^[2] ^[3] ^[4]

Function

ALBU_HUMAN 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.^[5]

Publication Abstract from PubMed

To improve the selectivity, delivery, and activity of ferric (Fe) anticancer agents, we design prodrugs based on N-donor residues of the human serum albumin (HSA) carrier IIA subdomain. We synthesized six Fe(III) compounds derived from 2-hydroxy-1-naphthaldehyde thiosemicarbazone (7-12). HSA complex structure revealed that Fe compound binds to the hydrophobic cavity in the HSA IIA subdomain. Lys199 and His242 of HSA replace the two Cl atoms of Fe compound, coordinating with Fe(3+). In vivo data revealed that compound 12 and HSA-12 complex inhibit the growth of the liver tumor and that the HSA-12 complex has stronger targeting ability and therapeutic efficacy than compound 12 alone. In addition, our results have shown that compound 12 and HSA-12 complex induce Bel-7402 cell death possible by several mechanisms.
