[[http://www.uniprot.org/uniprot/ALBU_HUMAN ALBU_HUMAN]] Defects in ALB are a cause of familial dysalbuminemic hyperthyroxinemia (FDH) [MIM:[http://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 == | |||
[[http://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 == | |||
Perfluorooctane sulfonate (PFOS) is a man-made fluorosurfactant and globally persistent organic pollutant. PFOS is mainly distributed in blood with a long half-life for elimination. PFOS was found mainly bound to human serum albumin (HSA) in plasma, the most abundant protein in human blood plasma, which transports a variety of endogenous and exogenous ligands. However, the structural basis of such binding remains unclear. Here, we report the crystal structure of the HSA-PFOS complex and show that PFOS binds to HSA at a molar ratio of 2:1. In addition, PFOS binding renders the HSA structure more compact. Our results provide a structural mechanism to understand the retention of surfactants in human serum. | |||
