The structure reveals how P-TEFb binds the aff4 scaffold, and the observed Cyclin T1-AFF4 interareionstronglyrongly supported by extensive binding studies using mutant Cyclin T1 proteins and transcription activation data using mutant aff4 proteins.
The mechanism of controlled conversion from right-handed to left-handed has been assayed by various dye binding studies using CD and fluorescence spectroscopy.
As predicted by previous in vitro binding studies using Drosophila Robo1 (Brose et al., 1999; Fukuhara et al., 2008), we found that deleting Ig1 from Robo2 prevented Slit binding in cultured Drosophila cells.
To understand better the regulation of SNF1 by ADP, we did a series of binding studies using the phosphorylated, active form of the enzyme.
The binding site of EMD 57033 in the human β-cardiac myosin motor domain was further defined by molecular docking experiments in combination with direct binding studies using myosin motor domain constructs with alterations in the predicted binding region.
Further, binding studies using S10 extract from HeLa cells, partially silenced for PTB gene expression, resulted in reduced binding by other trans-acting factors.
All of these binding studies used in vitro competition binding assays.
On the other hand, few studies have addressed the binding ability of PBDEs with TR, except for a competitive binding study using rat TR by Kitamura et al. (2008).
The specificity of this binding was confirmed by competition studies using cold wild type and mutant competitor probes.
