A serum prolactin-binding protein: implications for growth hormone
1Dept of Pharmacology, Yale School of Medicine, New Haven, CT 06520-8066, USA.
Abstract:
Many membrane receptors have truncated soluble forms that circulate in the blood, and a protein in serum with characteristics of the extracellular domain of the human prolactin receptor has recently been identified. Because the extracellular domain of the prolactin receptor binds human growth hormone, does the prolactin-binding protein in serum affect the amount of bound circulating growth hormone? A more general question is whether this serum protein has a minor or a major effect on the biological activities of growth hormone and prolactin.

Factors Affecting Protein-Drug Binding: Drug-Related Factors
One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In contrast,...
