Subject: Creb Rachel, Jerry Yin's Creb is NOT the same one as \*a Creb currently in FlyBase. It is dCREB-B (aka (d)CREB-2) with different isoforms a, b, ...., (alternative splice variants) and this and a close relative maps to 17A and 17B. But which is which is not known. It is not even clear that the different isoforms all come from the same gene. Sarah Smolik
