In vitro, hydroxylated PCBs have a low affinity for the human thyroid receptor but do have a TH-like affinity for the serum transport protein transthyretin (Cheek et al. 1999; Meerts et al. 2002) and inhibit the iodothyronine sulfotransferase activity (Schuur et al. 1998).
Collectively, these data validate AgRP as a scaffold for protein engineering and demonstrate that modification of a single loop can lead to AgRP-based peptides with antibody-like affinities for their target.
This whole strategy relies, of course, on the unlikely proposition that Etsy can, over the long term, compete with UPS and PayPal on price, or the more likely idea that sellers simply like Etsy and want their products affiliated with Etsy in a way they don't like or feel affinity for a corporate death star like Facebook, where anyone can pay to have anything promoted.
Furthermore, properties like the affinity for GABA and modulation by drugs such as the benzodiazepines and steroids is determined by the specific subunit composition of the GABA-A ion channel subtype (Lindquist and Birnir 2006; Olsen and Sieghart 2009).
In the original, this structure is hard to position, but in the reconstruction its position and angulation are more hominin-like, indicating an affinity for bipedal locomotion.
Recently, we described a triple mutant of the bacterial cytochrome P450 BM3 as the first mutant with affinity for drug-like compounds.
Characterization of the receptor binding pattern of H10 hemagglutinin from avian and human isolates showed that both interact weakly with human-like receptors and maintain strong affinity for avian-like receptors.
14 It is an irreversible inhibitor of the proteasome that seems to be more selective for chymotrypsin-like protease, with less affinity for the trypsin and caspase-like proteases in the 26S proteasome.
Personally, I feel a lot of affinity for efforts like this.
In this work, two-photon probes 1 and 2, bearing ifenprodil-like tails that have affinity for NMDA receptors of neuronal cells, were designed and prepared.
