|Binding, Transthyretin in serum|
Interference with thyroid serum binding protein transthyretin and subsequent adverse human neurodevelopmental toxicity
Pentachlorophenol is measured in mammals as parent chemical, hexachlorobenzene, and can bind to TTR, like other halogenated phenols (Marchesini et al 2008; van den Berg 1990). Halogenated phenols, such as PCP, have been implicated as thyroid toxicants (Miller et al 2009); however, it appears only 2,4,6-tribromophenol and pentabromophenol can competitively bind TTR (Weiss et al 2015).
