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
11-(Dansylamino) undecanoic acid (DAUDA) is a dansyl-type fluorophore and has widely used as a probe to determine the binding site for human serum albumin (HSA). Here, we reported that structure of HSA-Myristate-DAUDA ternary complex and identified clearly the presence of two DAUDA molecules at fatty acid (FA) binding site 6 and 7 of HSA, thus showing these two sites are weak FA binding sites. This result also show that DAUDA is an appropriate probe for FA site 6 and 7 on HSA as previous studied, but not a good probe of FA binding site 1 that is likely bilirubin binding site on HSA.
A fluorescent fatty acid probe, DAUDA, selectively displaces two myristates bound in human serum albumin.,Wang Y, Luo Z, Shi X, Wang H, Nie L, Huang M Protein Sci. 2011 Dec;20(12):2095-101. doi: 10.1002/pro.749. Epub 2011 Nov 9. PMID:21997768[6]
