Critical parameters in surface plasmon resonance biosensor development: The interaction between estrogen receptor and estrogen response element as model

Estrogen receptor interaction with estrogen response elements.

The estrogen receptor (ER) is a ligand-activated enhancer protein that is a member of the steroid/nuclear receptor superfamily. Two genes encode mammalian ER: ERalpha and ERbeta. ER binds to specific DNA sequences called estrogen response elements (EREs) with high affinity and transactivates gene expression in response to estradiol (E(2)). The purpose of this review is to summarize how natural ...

Mouse Estrogen Receptor b Forms Estrogen Response Element- Binding Heterodimers with Estrogen Receptor a

The recent discovery that an additional estrogen receptor subtype is present in various rat tissues has advanced our understanding of the mechanisms underlying estrogen signaling. Here we report on the cloning of the cDNA encoding the mouse homolog of estrogen receptor-b (ERb) and the functional characterization of mouse ERb protein. ERb is shown to have overlapping DNA-binding specificity with...

Advances in surface plasmon resonance biosensor analysis.

The number and diversity of surface plasmon resonance (SPR) biosensor applications continue to increase. Evolutions in instrument and sensor chip technology, experimental methodology, and data analysis are making it possible to examine a wider variety of biomolecular interactions in greater mechanistic detail. SPR biosensors are poised to make a significant impact in basic research and pharmace...
