Oncology Study of STAT3 Protein Interactions Using an In Vitro Binding Assay STATE UNIVERSITY OF NEW YORK AT STONY BROOK Nancy C. Reich Marshall ArmstrongJulieTranscription factors function as regulators of gene expression by controlling the activation of target genes. As a member of the STAT (...
This chapter presents a simple and quick assay to test the ability of candidate target proteins to interact with small GTP-binding proteins of the Rho family. It chapter describes the basic principle of the method using the GTPase-activating protein Rho鈥揋AP as a model system. The influence ...
In Vitro Protein Kinase Assay Service Protein kinase are enzymes that catalyze the phosphorylation of proteins. It can transfer the phosphoric acid from ATP and covalently bind to the hydroxyl group of some serine, threonine or tyrosine residues in specific protein molecules, thus changing the ...
Novel protein--protein interaction between Escherichia coli SoxS and the DNA binding determinant of the RNA polymerase alpha subunit: SoxS functions as a c... SoxS is the transcription activator of the SoxRS regulon. Despite being synthesized de novo in response to oxidative stress and despite the...

Pgp is a 170 KD protein with 1280 amino acids and 12 trans-membrane segments, expressed by gene known as MDR1 or ABCB1. ICE Bioscience generated MDCKII-MDR1 cell line in house by lentiviral system in-house, also developed permeability assay in both parental MDCKII and MDCKII-MDR1 cells....
COOH-terminal proline-rich domain of PTP HSCF revealed that a subset of prolines, as well as other residues, was required for efficient binding to PST PIP, and introduction of alanines at some of these positions in the protein resulted in decreased binding to PST PIPin vitro and in vivo....
assay, we found that although Kyn facilitated differentiation toward MkPs, Ahr knockdown switched differentiation toward EryPs (Fig. 6h). To validate the in vitro human results in vivo, we constructed a humanized mouse model by transplanting CD34+ UBCs into severely immunodeficient NCG-X mice, ...
Protein self-assembly is critical for numerous biological processes. Yet, assembly is rarely targeted by therapeutic agents, in part because it is hard to identify molecules that interfere with protein–protein interactions. Here, we describe a simple fl
To identify direct Hox targets, a considerable effort has been dedicated to characterise the DNA binding sites recognised by each Hox protein. Surprisingly, in vitro analyses revealed that all Hox proteins recognise a short 6 bp AT rich sequence that, on average, is found multiple times in al...
