== Disease ==
[[https://www.uniprot.org/uniprot/ALBU_HUMAN ALBU_HUMAN]] Defects in ALB are a cause of familial dysalbuminemic hyperthyroxinemia (FDH) [MIM:[https://omim.org/entry/103600 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.<ref>PMID:8048949</ref> <ref>PMID:7852505</ref> <ref>PMID:9329347</ref> <ref>PMID:9589637</ref>  
== Function ==
[[https://www.uniprot.org/uniprot/ALBU_HUMAN 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.<ref>PMID:19021548</ref>

== Publication Abstract from PubMed ==
The displacement of probes that bind selectively to subdomains IIA or IIIA on human serum albumin (HSA) by competing compounds has been followed using fluorescence spectroscopy, and has therefore been used to assign a primary binding site for these compounds in the presence and absence of fatty acids. The crystal structures have also been solved for three compounds: a matched pair of carboxylic acids whose binding strength to HSA unexpectedly decreased as the lipophilicity increased; and a highly bound sulphonamide that appeared not to displace the probes in the displacement assay. The crystallography results support the findings from the fluorescence displacement assay. The results indicate that drug binding to subdomain IB might also be important location for certain compounds.

A combined spectroscopic and crystallographic approach to probing drug-human serum albumin interactions.,Buttar D, Colclough N, Gerhardt S, MacFaul PA, Phillips SD, Plowright A, Whittamore P, Tam K, Maskos K, Steinbacher S, Steuber H Bioorg Med Chem. 2010 Nov 1;18(21):7486-96.
