Published in Gene Therapy Weekly, November 9th, 2006

According to recently published research from the United States, Nore1B regulates T cell receptor (TCR) signaling via Ras and Carma1.

"Nore1A was originally identified as a potential Ras effector, and Nore1B is an alternatively spliced isoform. Both share a Ras/Rap association domain (RA domain) but only Nore1A contains sequence motifs that predict SH3 domain binding and diacylglycerol/phorbol ester binding in the amino-terminal region.

"Here we report that Carma1 binds to Nore1A and Nore1B through the RA domain and that Carma1 interacts with active Ras in the presence of Note1B. RNA interference against Nore1B attenuates NF-kappa B activation...
